Rear motor mounts

[Dcolumbia]

So I ended up cutting the nut off the bottom of the right mount but like Mr hagg said, the threw bolt is froze in the mount. A huge pain to get to a couple of the bolts on the tranny because the mount was in the way. The left one looks really tough because of the starter and the clutch linkage. I heated that one up several times and the nut finally came off but the bolt is of course froze in the mount. Looks to me that if I could get that bolt out I might be able to slip the mount out to the rear without pulling the top bracket off of the tranny. Any suggestions?
