225 slant 6 exhaust manifold

My dad has a 1977 Aspen with a 225 in it. Looking for an uncracked exhaust manifold.
Thanks

I have several, but they're heavy to ship. Also all of mine have the obligatory 3 broken fasteners that every one of them have that join the intake and exhaust manifolds together. If you can deal with getting those out, I have some good ones. If you cannot, I suggest you look at some of the overpriced new ones, as every used one you find will likely have those broken, as well as the heat riser flap frozen. If you can deal with and repair those things, I have several that are uncracked.
