Hi all. Noticed an issue I believe was brought up before but can't find the post. Anyway, I recently replaced my rear seat bar links in my TB and noticed something troubling. There is some rust on the rear upper control arm about half an inch below the bolt hole and an actual hole about 3/8ths in diameter on the driver side!! I've always tried to keep the underside clean since I bought it so this is the only trouble spot I've seen. Frame is in excellent shape for the year otherwise. Was thinking about removing the bars and derusting the entire area on both sides and hitting it with some rust reformer. I know the hole will eventually have to be welded but I need to stop the rust from spreading before the arms decide to let go of the frame. Will rust reformer work? Any experience with it?
