First off I would like to say HI. I'm new here. I just purchased a 1984 bmw 528e in pretty good shape for 70 bucks. It has a bad drive shaft support. I did some search and found a little bit of info on the problem I'm having but had a few more questions. First off I was not thinking when I pulled the drive shaft apart and did not mark it so it is going to be out of balance. I was wondering if a local shop would be able to balance this drive shaft or if i should just purchase a new one that is prebalanced. Also the drive shaft support is held on by that c clip with a metal round piece that fits down in the support bearing. The metal piece was all bent up when I pulled the drive shaft off. I ordered the support bearing but do not thank it comes with the metal piece does any body know where i can order this piece from.
