These are a bit different on the SS/SC. Support your tranny like in the picture, with a hydraulic jack. (if you put the jackstands behind the front tires and remove the floor jack, you'll have more room to work).The rear mount is 3x18mm bolts in the bracket, one of them is the bolt that goes through the insert. There are 3x15mm bolts in a triangle pattern that go straight up through the frame. We also have a heat shield near the DP, you'll see it when you take a look under there. The front mount is 3x18mm bolts, pretty easy. I removed the old inserts by putting the mount in a vice, and pounding the inserts out with a sledge hammer. It only took about 10 whacks and it came right out (and got some agression out). Putting the solid inserts in was a bit tricky, but easy. First, put a bit of all-purpose grease on one side of the insert. Keep the mount in the vice and push the greased side in by hand. Now whack the side that sticks out with the sledge. Don't cut that rib off! And when you pound the new one in, remove the metal piece in the middle. It was pretty easy, it took me under an hour to do them both. Just do one at a time.

A Bench Vise works pretty well too! Lube one side and insert the bushing sideways with the lubed lip in past the bevel in the mount, crank the old vise and walaa they pop right in

I would just like to add that if you don't have access to a vice, a C-Clamp and a couple thin pieces of wood will do just fine t o press the bushing into the mount
