my brother busted one off his trooper and did the jb weld thing(after it was installed). no one is going to sell you just a housing cause they rebuild the cores. jb is still holding and we have pulled it once since. as far as getting it in, thats the fun part. takes two people and a litte wiglin, jukin, and such. sometimes it helps to take some of the engine mounts off so you can tilt it to make it easier.
