first remove the bolts
jack up the section you are working on
then remove the mounts
put the new ones back in with new hardware is possible
you may need to replace the core support bushings as well

good luck

I had to remove my gas tank in order to get at the rear cab mounts. I used a jack and some lumber under the outrigers to jack the cab up in order to remove the bushings

the metal is all rotton and missing on the back two supports so i need to replace them and my pssenger side is shot to...they are filled in with that expanding foam and i dont really like that.. i need to tell my dad the procedure on how to do this so he will let me start doing it..hes kinda anal on some stuff and hes worried that my ability on this stuff but i dont think its that hard...ill prolly have to move the tank out to... but i dont need to weld the new ones in do i???

the cab supports are welded in place with spot welds from the factory. they will need to be drilled out so you can remove them. also you will have to weld the new supports back in.
