When I was looking for these manifolds a couple of years ago, I thought that the new ones were $599, but I could be wrong. I bought one by itself, drivers side, then found a passenger side with a broken bolt hole, the front. He had the piece broken, and I had Ostrich Racing weld it on professionally. I think that I had $75 in that one, including the welding. I got lucky, and you really have to look to see where it was welded.
