90 gtu 5 speed, started takin my trans out the other day and noticed one of the bolts on my trans mount is broken inside the body and im a little nervouse about breaking anymore bolts. do these bolts go into the cabin or are they goin into the subframe or something where i wont be able to get to them.

 

Pull the carpet. They go out the other side. Odd you broke such a large bolt, I suggest you use a torch to heat them up if rusted.
