How will we ever know we ever know unless I mock them all up and take pictures? You are a bad influence lol.
I now remember the angle milling of the C body manifold coming up in the other thread. Do you know if they milled the other side of the flange ears to mate the bolt square to the flange? I still think it would dump the exhaust out in a less than ideal location.
Also one caveat...when I think of something not working in a BB a body it is due to the mechanical clutch linkage about 50% of the time. YMMV with a slushbox : D
