alright...I got the bolts out of the body mounts (except one so a cutting my trunk I go oh well)....what is the best way to go about replacing the mounts and what do I need to disconnect??? steering perhaps??? will the rear bumper be in the way of jacking up the body??? where is the best spot to jack up the body??...Thanks is advance...Paul

You should leave the bolts in one side, loose. Use a 4x4, 2x6, etc. under the floor braces on the other side. Use a floor jack and lift that side just enough to slide out the old bushings and slide in the new. You may have to get fancy, like a 2x4 upright on a floor jack to get the ones under the trunk loose. Lower that side down, install the bolts, leave them loose then do the other side. Then go around and tighten down all the bolts to proper torque. No need to disconnect anything.

It's not that hard once you have all the old bolts loose.

thanks for the replys....I am going to try this tomorrow hopefully......which is prefered the pinch weld or floor board braces for the jacking point....

Just want to thank everyone for there help along with the stickys in the tech area...got the new mounts in.....went with jacking on the pinch weld area to lift the body and it worked like a charm....so did the PB Blaster on the bolts for like a week before I tried to loosen them....its time to fit the Tremac......can almost hear it starting now.....Paul
