Well, it depends. Are you replacing with stock rubber bushings or PU? Getting the old ones out is not a lot of fun. Some people burn them out. That was way too toxic for me. I used a drill and made a million holes in the rubber until it gave way and I could pull it out with some pliers. Check the instructions of the manufacturer of the new bushings to see if you need to re-use the outer sleeve of the bushings. IF you do, you may be better off having the bushings pressed out by a shop. If you don't need them, get the rubber out of the way, carefully use a hack saw to cut a groove in the casing, and then you can peel it out with a screw driver and hammer. Don't cut into the control arm! PU bushings go back in fairly easy. When I did the stock rubber ones on my '70 I had a shop press them back in. Marty
