Z28 exhaust manifold crack opinion

FWIW the exhaust manifold with the "raised walls and rivet bosses" for the preheat shroud and without the provisions for smog are not correct for any 69-73 Z28.

I was just using this "other" cracked manifold as a test candidate. I have a SS350 4-speed, so it uses the same smog manifolds as the Z.

Buying a repro might be the way to go now and just use the one original side that is still good.
