I just started taking my old body mounts off today and it looks like it might be a little more work than I expected. Most of the nuts came off fine but three of the screws broke. I got all of the rubber and washers on the bottom half off but some of the sleeves are rusted to the screw. Does anyone have suggestions as to how to get the sleeves off? I also noticed the screw for the mount that goes through the floor by your feet is welded to the floor. Do i grind that weld off and remove the screw or can i jack the body high enough to get the upper rubber mount out? I haven't looked at any of the other screws to see if they are welded to the floor. I just figured they were carridge bolts. Also, does anyone sell a bolt kit for body mounts or can i get all the bolts from the hardware store? On a different subject, what inlet/outlet do you guys use for your mufflers? It looks like a center/center would work for my 71 Blazer. Any help is greatly appreciated, as I am getting very close to getting my truck on the road after 2 months of wrenching. Have a nice memorial day weekend!
