It has been years since I've been here, but I'm trying to look up some info. There was a guy that made tubular trans cross members for the 4L60 and 4L80 in GM trucks. Space and weight savings. I spoke with him when I was thinking of an 80 swap.
I don't know where I spoke to him. Here, performance trucks, FB RCSB, can't remember. Anybody know the "guy". TIA
