need body mount help

[Swartzhund]

I'm in the proccess of swapping the rusted shell off my 86 k10 with a much better 87 c10 donor. The body mounts came off the 86 pretty easy exept the cab. I tried an impact on the rear cab mounts and they wouldn't budge....ended up torching the hell out of them to cut them out.

My question is: If the ones on the donor are like this what is a good tip for getting them apart without cutting it apart?

Do you mean the body mount bolts?

[Swartzhund]

yeah, but to torch the bolts I ended up burning the rubber mount and cutting into the cab support.

[bigblock73]

How about cutting off the bolt head, removing the cab, and taking the rest off when you have better access to them?

I have found that wd-40/liquid wrench, a propane torch, and a big breaker bar will loosen just about every stuck bolt. Working the bolt back and forth will help loosen it as well.

A strong breaker bar, another bar to extend it so you have alot of leverage, and snap the bolts

[Swartzhund]

I'll try that, I already broke an extension because I couldn't get the breaker bar in there without it. But that was all 3/8" stuff. I'll go bigger next try!
