Cab mount mounting hardware ????

[66 lwb cs]

Ok so I did the search and couldn't find an answer, I installed my new C10 mounts on my C20 cab but ran into a problem. When I installed the bolt that goes into the bottom of the cab it is completely bottomed out but the bottom rubber piece never compressed. It will spin slightly by hand. I assume this is not right and am wondering what to do. I know I can put a stack of washers on it but not sure thats the right way to fix the problem. I went to Home Depot for a zinc coated replacement to my O.G. bolt a while back and they had nothing like the bolt for the C20 mounts so I'm not confident that they will have anything similair to the C10 bolt. I tried the C20 bolt but it is too short. The rubber pieces are in good shape and are not mashed down and distorted at all when not installed so I am at a loss. Any help appreciated. Thanks in advance.

i just changed my mounts from c20 to a c10.. i got new cab mounts and the kit came with the hardware. i had to remove the original nut and replace it with the one in the kit. the nuts are in a small housing under the gas tank i removed them and put in the new one......... you can see one from the passenger side

Perhaps I should have specified my whole kit came from an original 66 C10 so the bolts and hardwar were for mounting in the original mounting hole. I did not purchase an aftermarket kit so do I need to drill everything out and go in from the top?

If you areusing original hardware and the bolt is bottoming out in the nut, you must be missing a plate or washer somewhere. Is this on both sides? Maybe if you could post a pic of what you have in your cab mount assembly, we can see if something is missing.

Will post this weekend away for work right now but what I have is the bracket to rubber spacer rings and 2 plates that go on top of each ring and the bolt I have not mounted the other side yet still have to chisel out OG part but will look at the bolts maybe they are different lengths thanks.

What height is does the cab sit off the frame?
Do they give you a measurement in the kit?

Does it fix the broken back using c10 on a c20

LostMy65 something around 1"+, did my K10 last year.
Mind you it's for a 60-62 frame. Courtesy of 1Bad62Pro/Street

Thanks aero,
I modded the pic you attached:

The reason I'm wanting that measurement, is I'm thinking about making my own perch.
I think $80 is a little steep for a couple of brackets.
Here is mine since the original rubber has separated from the perch:

Could someone get me this measurement?

[Captainfab]

I don't have any C10's that are assembled. Would the measurement from the top of the frame to the top of the rear mount bracket do you any good?

Actually, I see now that aero went back and edited his post to say 1"+.

But yes, if you could get me that measurement it would help.

Oddly, the measurement on the schematic he attached and this one, both show the brace itself at 1.06.
(63-66)

[LostMy65]

But then again,
this appears to show the mount bracket at barely over an inch.
I bet the bracket is as the schematic shows it and should be mounted at 1.06" above top of frame.
Here it looks as the measurement I'm looking for is around 2" (top of frame to bottom of cab support)
Honestly, it isn't that critical. I'll mount it slightly low. I can always ad a plate spacer or two if needed.

2.12" looks to be the height from top of frame to bottom of cab support:

Can someone give me the length of the rear cab bolt for a 66 C10. The kit I bought from Brothers came with a 1/2 bolt it should of been 7/16.
Thanks for the help
