I would like to sell them as a set do not need sitting around and think pair is easier get rid of than single. I restore and work on older boats ended up with these sitting around after some projects have no use for them.
These weigh 60 lbs each so buyer pays actual shipping. I have here one pain of Barr manufacturer big block v gm inboard exhaust manifolds for a Mercuries v-8. Gaskets are with them as the studs and nuts for manifolds. They are brand new in the box and have never been mounted or used any way.
These cost well over three hundred dollars each.
