No.

I had to saw off a useless looking boss (on the tranny) that touched
mine.  Actual experience seems to vary.  I'll photogrpah the bit I cut
off and a spare tranny one of these days I promise.

Aaargh.  I cut up an 87.5 recently, and I think I couold have measured a
few more things... so much of the exh wouldn't come off nice I didn't
bother...  Anyway, *as I recall* and I could be wrong it looked like the
whole system was a larger diameter.

So my opinion in the matter - if you're going to swap the manifold, and
undoing those nuts is gonna cost more than any used manifold you buy,
use the 4kq parts and go to meineke or whoever to build the rest -
perhaps using the cat & back parts from the 87.5? - then only one piece
has to be mfr'd.

Of course if you think you can get the old manifold off without
committing hari-kiri, (remember this has to be done twice, once on the
donor as well), or if the head will be off... and if the 87.5 stuff is
cheap enough (free?) then it might be a fun project.
