I'm throwing a junkyard 700R4 in my GTA to get running again. The torque arm bushing is pretty used up. Has anyone found a source other than the dealer? Are there any good aftermarket pieces? Thanks.

 

Yes, there are aftermarkt ones available. I have had mine for awhile and I don't remember where it came from, Summit I beleive. They are cheap, tough, and long lasting. They look nothing like the stock one. They are a little tricky to install since they are much bigger. But if you need a new one, I wouldn't go any other way then the Polyurethane.

 

You can get them from summit, you do need to know which way the torque arm fingers face, they can be in or out.
The end of the torque arm looks like an M on its side, some face in and some face out.
