I got my first set of subframe bushings from Brian C King, in a group buy on this website. Second set I bought was from a guy named Bruce Malchuck, probably spelled it wrong, on ebay. They were both about the same price, 90-95 bucks.
I posted a while back about a FSTB, and the only reply I got was Bob G. He has had a lot of problems delivering though, and a few people are still waiting for braces after six even seven months. So I definately would not do business with him.
If you find out where to pick one up, let me know also.
Take care
