I'm looking for a pair of stock two bolt style, exhaust manifold flange/ collector ends off from a small block 273 cid. a buddy of mine needs them and I unfortunately tossed the ones I had, so I'm trying to help him out. They must be in good usable condition with mounting bolts if possible. I can't remember if they had spring'd bolts on them or not. if possible leave several inches of the pipe on them. Thanks!!
