Cab swap questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I've searched in vain and can't find a clear answer to these questions...

Will an 82 2x4 1/2 ton cab mount to an 85 4x4 3/4 ton cab without any issues other than the different transmission hump (which I would be changing to accommodate the 4x4)?

Is the cab mounting hardware different between 82 and 85? I've seen on LMC truck that the mounting hardware they sell comes in different sets for 81-83 and 84-87.

I need a rust free cab in the worst way and the 82 I've found will work as long as it will mount without having to do a lot of modifications.

the trans hump is the only problem you will have. and you will probally need to use the 82 cab mounts.
