not to second guess someone but I believe the "LS1" manifold 1BADC10 used on his driver side was an odd triangle and not like the truck...

Oh wait, are we talking where the manifold bolts to the y-pipe? That I'm not sure about. I thought we were talking about the flange from the manifold to the head.

yea I meant y-pipe, was trying to narrow it down.. sorry for the confusion.. We put a ls1 in a 94 and are having a hard time finding the flanges.. it is all we like to get it running and no one around here seems to have any.. I can order the whole y pipe from GM for 400 bucks but was hoping to find it cheaper..
