changing body mounts?
are your body mount bolts welded to your body as well? if so how do we switch out the bushings without completely lifting the body?

Your body bolt's should not be welded to the body if so I would cut off the head of the bolt and replace the bolt's when you replace the bushing's..

Finally something I can comment on. I just finished replacing the body mounts in my 72. Yes each bolt has a spot weld to help secure the bolt. I took a cut-off wheel and cut the heads like pizza and used a cold chisel to break them off. The ones in the floorboards are sunken (sp?) in recessess. I used a cut-off wheel and tried to make a cross that went through the middle, and then used a large drill bit to drill the head of the bolt off. I ended up having to use the chisel to finish the break of the head. I used a grinding stone on the end of a die grinder to clean off the spot weld.
I did one side at a time. I used a floor jack and some pieces of 2 x 6 (to spread the weight) and lifted each side of the body. It really wasn't that bad of a job. I got the mount kit from Tim Christian and it was perfect. I would suggest getting a very good quality drill bit for the bolts going through the floorboard.

Yes, the body bolt heads are tack welded to the floor from the factory. You can grind them, although the recessed ones can be tough to get at with a grinder.

Mine were tack welded to the floor too. I just center punched the bolt heads and drilled through them... used a 1/4" punch to drive the bolts down through the mounts and an air chisel to knock the heads off.
