to say "and your problem is?". Every one of the one piece manifolds
I've looked at has similar cracks. Unless it's letting exhaust leak out
of the manifold there's no harm done.

That's exactly correct.  There are no other cracks in the manifold and this
one is a hairline crack in the base of the Y-shaped flow divider.  Otherwise
the manifold is in very good condition -- it was removed from a car that was
involved in a serious accident but was running well at the time.  According
to the seller, it was installed as a dealer replacement for a cracked
one-piece several years ago.  I want to use it on the rebuilt engine I'm
putting in the '86, along with Ben Swann's chip and wastegate spring.
