65 Burb body mounts

[jekyllandhyde]

Do the rectangular mounts come with the round spacers? I see the square ones do. I am assuming the square ones are for the cab?

I called the Truck Shop last week and the woman that I spoke with said they don't carry any body mounts for a mid 60's Suburban. Did the kit happen to have a part number? If so, could you post it? I have been looking for body mount cushions for over 6 months. It's great to see that these are now available.

Called Truck Shop and they said the P/N is: 6009605. Supposed to be in the 2015 catalog, I don't have mine yet.

Page 89 of Jan 2015 catalog. Don't see it in their on-line catalog yet...

This is great news! Thanks for sharing here.
You said they are thinner, what is the thickness on the rectangular ones?

From Ron's post <from Lewis>: "...1964-6 body mounts are p/n 3794779, w/dimentions of 1.76" w; 3.00" l; 0.92" thick, needing 8 (up & lwr same)."

Thickness includes the raised half moon portion of the rubber, i think, so the rubber thickness listed for original ones are supposed to be ~3/4"?

[Acsb1]

hi there when you call the shop or go there ask for Steve or Mike they are the Suburban guys. Not sure if there is a part number yet, I understood they got the first 3 sets in last week, maybe they are gone already but mike said they will have more coming in this week

[Grandpa54]

I bought a set today, it took about 10 minutes on hold but she came back and said they had them. I should have them in a few days.

[66 Burban]

I got the last set of the first six sets today --- should be in my hands early next week. Steve said more to arrive shortly.

[Grandpa54]

Got mine today they are pretty thin!

[jekyllandhyde]

I picked mine up yesterday and was able to lay them out this evening. They are a little thinner than the stock ones as Grandpa54 pointed out. The material looks to be a little denser, or that might just be because they are new. All in all they are a fairly solid reproduction.

I have one question though. There are a total of 8 of the large square cushions. I know that four of them mount at the floor board location in the front cab. The other four I can only assume are for a panel or not required for a Suburban? Not sure on those. I went through the photos of the disassembly of my Suburban and the only other body mounts are the ones in the front of the frame for the core support. Obviously, the square cushions won't fit there. Any idea on those? I hope I am not missing something that's sitting right in front of my nose.

the height of the insulator excluding the raised part is .720"(23/32"). shy of 3/4"

Ron,
I assume you are talking about the original mounts vs the new repro ones? Anybody who's got a set in hand, can you measure the thickness, please? Folks say they are "thinner" than original. Called Truck Shop and they didn't have that info handy... none in stock ~2 weeks ago.

According to Steve, I got the last set until new shipment arrives.
Just checked one of mine........
Without raised section: .594" to .610"
Raised portion: .682" to .704"
The rubber does seem to be higher durometer (denser), and should not compress as much.
So, we're talking about less than .10" difference --- should not be a problem..

Billy: are are you saying .010 or .100" which is closer to 1/8" which could cause a few alignment problems such as doors if you are using the regular front body mount insulator.
these trucks though were well compensated with the use of shims to tweek theses sort of adj.
It does look like they are selling a complete suburban mounting kit and the others are also perhaps compensated for in height

Thank you!

Another favor, can you measure the two hole diameters from your Truck Shop reproductions?

Here's what I think they are supposed to be:
my measurements from old mount
rubber side hole diameter - ~0.75"
steel side hole diameter - ~0.44"

(Chevy parts book, ron, lewis)
length - 3.0"
width - 1.76"
height (thickness) - 0.92" w/ raised portion, 0.72" w/o raised portion

Thx,
Roy

I've call the truck shop a 3-4 times, and emailed them. When I get thru, they didn't have the mounts in stock to measure, or I'm on hold for 15-20 minutes and never get thru. Can someone with a pair measure the 2 hole diameters? Just want to make sure.

Thx,
Roy

I finally got mine from truck shop so I measured the rectangular mounts:

Here's what I think they are supposed to be (Chevy parts book, ron, lewis) Truck shop measurements in blue:
length - 3.0" Truck Shop - 3.25"
width - 1.76" Truck Shop - 1.9"
height (thickness) - 0.92" w/ raised portion, 0.72" w/o raised portion
Truck Shop height - 0.69" w/ raised portion, 0.59" w/o raised portion
rubber side hole diameter - ~0.75" Truck Shop - 0.76"
steel side hole diameter - ~0.44" Truck Shop - 0.62"

Have not installed yet, anybody have a problem with them fitting between the rails, since these are a little wider?

And the diameter of the steel side hole is much larger, looks like it'lll make for a sloppier fit for the bolt?

I finally got to replacing some of my rubber body mounts with the Truck Shop ones. I used the square ones with the sleeves on the frontmost cab mounts. Good fit, previous ones were round, I assume replaced at some point. Don't have the fenders on yet, so don't know if I'll need spacers for added thickness.

I used the rectangular ones to replace my rusted ones in the rear positions. They do fit between the rails, was concerned with extra width. Comments on the install of the rectangular ones:

• No sleeve hardware provided, gotta find your own.
• Raised half moon sections were too low, didn't really make a good positive interlock with the other mating half. OEM height was 0.2”, these are ~0.1" or less. Some were taller than others, not consistent.
• Larger hole on the steel made for a sloppy fit, but not a big deal.
• Thickness was less than original parts (not quite 1/4" less), you may need to use spacers

[padresag]

these mounts have changed over the years. the spec that I have given were for the years 60? and 63up to 66. the orig part number superseded in the 67 - 72 series where that hole size i believe did change a little. this insulator has been used up to 2002 in jimmies and blazers in various models and that hole size may have varied again somewhere and the nbr was superseded again in there somewhere. one may have to bush that hole back down to size and get on with it. if they are not thick enough, what is a couple of more shims for these trucks that you love. sometimes you may have to improvise a little
truck shop won't sell to me or any other Canadian it seems. they don't want to ship to us and their telephone nbrs don't work from here. some places don't like to ship overseas. that has been the excuse a few times I have heard.
the ones from 2002 are also obsolete and I think that they wanted about $25.00 ea for them

I think that the real square ones were 60-62. perhaps someone could confirm that pls?
ron

[padresag]

here are the sizes for the bolts that go through the rear body mounts. Jon (60-66) looked it up. the part nbrs were taken from the assembly manual and you can see them there.

3771357 No 2 , 3/8 16tpi x 8 1/2" square neck
3771358 No 7, 3/8 16tpi x 5 3/4" square neck
3810759 No 4 3/8 16tpi x 4"
3811750 3/8 16tpi x 5"

I know this is over a year old, but I can't seem to find this anywhere else. I'm doing a 66 Panel and don't have my hardware. So I'm trying to make sure the bolts are the same, plus I need to know the sizes of the sleeves/spacers.

ron posted bolt sizes on this thread. I assume panels are the same...

My understanding is you won't need sleeves if you use the reproduction ones from Truck Shop. I finally got a set from Truck Shop and will measure the hole diameters. And spacers will depend on if you need them for lining up body panels, fenders, doors.

i did work her with offline and she does have the truck shop ones. the frt bolt behind the "B" pillar is different length if I remember correctly between suburban and panel

[padresag]

back to the assy illustration on line 75 there shows a sleeve that goes in the rubber hole around the bolt. they may refer to that as a spacer in the writtn descrition. this fills in the differential in sizes. and use shims as required.
I spent a bit of time going back and forth with Michelle911 about putting his/her body back on and got it done and off to the body shop. I asked if they would write a little note about the experience for others but only see silence. it is a one way street for a lot of people

these insulators were superceded several times over the years. as I said previously the square mounts I believe were used in 60-62. the rectangular mount was also used from 67-72 in suburbans but only see a listing for 69-72 for rectangular insulator part # 69-09703(truck and car shop). don't know what happened to 67/68. wonder if that is the same size as the earlier insulators in the 60-66 kit?. that insulator was used for 42 years.

no longer making them whats next going to try these it has our trucks listed as to fit http://www.energysuspensionparts.com/3.4149
