I've spent the last 24 hours doing EXACTLY this. In fact, I pulled the 2.0 engine with one mount (PITA to get off!!) last night and the other this morning. I then put them in my car and drove them to another members house, where he gave me a set of 2.3 mounts. I came back and have been screwing with it all day. I just gave up for today, since I THINK I need a Fox tranny crossmember part to get the T5 in. In fact, that's what I came here to search for....lol... I'll get to that in a minute, though.
Anyway, the biggest PITA about the mounts is the fact that the spot weld don't drill out THAT easily. Well, they didn't for me. I used a 5/16" or 3/8" bit and I STILL had to hammer the crap out of it to get them off. There are 5 or 6 on each side of EACH mount, and about 20-24 total. The lowest ones, where the frame bends a bit, are especially crappy, and I ended up just ripping off the mount there. The brake lines need to be shoved out of the way a little, too. You see all this when you get there!
What tranny are you putting in, and if it's a T5, how is it going to mount to the factory X-member? I don't have a Fox x-member, and I think I need one...
