wanted: control arms 71-72 C/10 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

mcmlxix · 09-08-2003, 04:11 PM

I was thinking about starting to collect the parts to rebuild the suspension on a 71 C/10. I want to sandblast and powdercoat without having the truck down.
This is just an idea but If any one has a set of 4 (upper and lower) control arms send me a price with shipping to 10310 (business address)
Thanks

MOTHERTRUCKERS · 09-08-2003, 06:24 PM

240.00 powder coated gloss black including shipping.

mcmlxix · 09-08-2003, 10:57 PM

I have my own sandblaster and powdercoating equipment. I want to do it cheap myself.

MOTHERTRUCKERS · 09-09-2003, 08:19 AM

O K non coated 110.00 with shipping.

cwilli84 · 09-09-2003, 09:08 AM

Mother trucker , do those arms come with the shafts installed on them. Let me know

MOTHERTRUCKERS · 09-09-2003, 10:22 AM

Yes they do, the ball joints are in them also.

clean71 · 09-09-2003, 01:42 PM

I'm looking for a set of lowers. Anybody have those? How much shipped to 85367? Thanks.

alta-aj · 09-10-2003, 01:32 AM

I have a set of lowers. I'm looking for $70 + shipping.

ucmydust68 · 09-10-2003, 09:08 AM

i have lowers. just pulled them off, 50 + shipping!!! pm me if ya want em!

clean71 · 09-10-2003, 10:31 AM

Forgot to ask. Ineed these for my 68. Are all the arms the same? Thanks.

ucmydust68 · 09-10-2003, 10:32 AM

im not really sure, these have disc brakes and i think that 68's are drums so they might be different

jmanz69 · 09-11-2003, 09:08 PM

I have a pair from a 69. It had drums, and the drum and disc ones are different, but only for the lowers. Mine need blasted, but are cheap. Only $25 plus shipping. They also need new ball joints and shafts too.

mcmlxix · 09-11-2003, 09:44 PM

I thought all the arms were the same, upper and lower. I thought it was the ball joints that made them fit drum or disc spindles. If you look at all the drop spindle options, I think it says 67-70 must use 71-72 ... wait, maybe that was tie rod ends ... help... one of the parts guys should know .... mothertrucker, wes,rick ???

jmanz69 · 09-11-2003, 09:48 PM

It's the steering stops and the ball joints that are different. If you use 67-70 lower control arms, you will have a very wide turning radius. The 71-72 arms are a slightly different design, that allow for a sharper turn radius. That is the difference between lower arms. 67-70 arms can be used to change to disc by changing the ball joint to a 71-72 type, but you will not be able to turn as sharp.

MOTHERTRUCKERS · 09-11-2003, 10:06 PM

mcmlxix Not ALL drop spindles need tierod or ball joint changes! Check the suspension section of our online catalog.

cheyenne10 · 09-12-2003, 12:54 AM

Can someone confirm that 68-70 a-arms are differnt than 71/72 version. That would change a lot for myself as well as others.

jmanz69 · 09-12-2003, 07:07 AM

Why don't people believe me... Anyway, here are pics to show the difference. The first is a 71-72 arm, see how the steering stop is rounded off at the top....

jmanz69 · 09-12-2003, 07:09 AM

This is the 67-70 style. The steering stop is more pointed. That and the ball joints are the differences. You can use 67-70 lower arms with no problems, and you probably won't really notice much difference.

mcmlxix · 09-12-2003, 09:02 AM

I believe you ... so what makes the truning radius so large? And when you say large, how large? can you still make a u-turn in a two lane street or do you have to make an X-Y-Z turn? (X-Y-Z turn means back and forth 26 times just to turn around)

cwilli84 · 09-12-2003, 09:06 AM

I thinkits due to the indicated bumps hitting the inside of the spindle and decreasing the angle at which the tire can rotate inboard/outboard. I think I got this right.

jmanz69 · 09-12-2003, 09:48 AM

cwilli you are right, the disc spindles hit differently than the drum spindles do. Each control arm was made to work with the correct spindle. But you can still turn. I don't know exactly how much wider your turn radius will be. I am using the 71-72 spindles and the 71-72 control arms.

mcmlxix · 09-12-2003, 10:05 AM

so if you "adjust" (read: cut,hack,torch,beat) them, the turning radius issue will be solved? It has nothing to do with the over all length / width / design of the arm itself?

jmanz69 · 09-12-2003, 10:35 AM

Correct, if you beat the hell out of it, it will work. I have heard of people doing it. There is no difference in size lenght or anything. Just the steering stop and the ball joint.

cheyenne10 · 09-12-2003, 12:38 PM

Sorry if I offended anyone. I just wanted to confirm what is being said. I studied your pictures and I see what you mean on steering stop.

Now that said does a stock 71-72 truck have a shorter turning radius vs the earlier ones which turned a bigger circle? It was stated above that "you will have a very wide turning radius" or is it a combo of early lower arms and new disc spindles that increase radius over stock drum setup.

Bottom line is I want tight turn radius and disc brakes with 2.5" lowered spindles. I only want to do this once.

thanks for all advise.

Sorry if this dettracts from original post on collecting suspension parts and price.

jmanz69 · 09-12-2003, 01:18 PM

I believe it's the combo of the early arms and spindles and the 71-72 spindles and arms. Each was designed to work with the other. Meaning the 71-72 spindles were meant to work with the 71-72 lower arms. If you use aftermarket spindles, ask them what year they work with. Some spindles are made to work with the 67-70 arms. Which means they should have the turn radius in mind. Hope this helps. and good luck.
