Rear Cab Mounts?

Are the rear cab mounts on a 63 3/4 ton interchangeable with 1/2 ton mounts? I know the brackets are different but can they be swapped and still line up?

Re: Rear Cab Mounts?

This is correct. I have a 3/4 ton frame I'm putting 1/2 ton mounts on. Just ordered a set from LILRED66 (Tony). Just grind off the rivets and bolt the other mount in place. Everything lines up.

Does anyone know what was the theory behind the C20 Shear Type Mounts?

Re: Rear Cab Mounts?

I think it was to provide a softer ride, they seem to have quite a bit more give than the 1/2 ton mounts...

That's what I was thinking.
The 3/4 ton is obviously a jerkier ride.

Re: Rear Cab Mounts?

it was used to give more of a floating action to any of that style cab above a c20 due to the more rigid suspension
