Differences between C10 and C20 cab mounts?
I need new cab mount bushings for my 71 GMC C20 and one site shows that they are all the same and LMC shows different pieces for the C20.
Does anyone know exactly what the differences are?

The C-20 rear bushings are taller because the frame brackets sit lower on the frame. LockDoc

Re: Differences between C10 and C20 cab mounts?
I believe you'll find the cab is the same, it's the mounts on the frame that are mounted differently as LockDoc said. So you order the bushings for the frame.
So if you have a C10 frame & a C20 cab you order C10 bushings !

Re: Differences between C10 and C20 cab mounts?
The factory drawing for the C-KA10 is incorrect in the fact that they included the Ks in the mix. All 4X4s whether they are 1/2 ton or 3/4 ton had the taller rear cab mount pictured in the C-KA20/30 drawing. WES
