1/2t to 3/4t cab swap ???'s - The 1947 - Present Chevrolet & GMC Truck Message Board Network

what else besides the cab mount bushings is different?
once I get the mounts I should be able to just slap my cab on the 3/4 frame right? or is there more that needs to be changed
what is the difference between 1/2t and 3/4t cab mounts?

The cabs are the same, just the rear cushions are heavier, & the brackets for the cushions are mounted lower on the 3/4 ton....just use the cushions for the 3/4 ton frame, & you should be ok. crazy longhorn

so only the rear mounts are different and I can use my 1/2t front and rad support cushions?
cos I got the rear ones are still on the frame

Im not positive on the front mounts, but beleive they are the same on both 1/2 & 3/4......the rear mounts are about 3 times as tall on the 3/4(a little suspension on the cab, to smooth the bumps!)......crazy AL

Yeah it's only the rears that are different.

You didn't mention if the 3/4 ton was a 4x4 or not but just check to see that the transmission humps are the same.
