I need some assistence on the underside of a LS1 vert. I picked up a 95 LT1 shell to rebuild my totaled LS1 vert. I cant look at the LS1 shell since it was crushed badly. I know when doing a LT swap to LS swap you need to drill spot welds out of the part of frame and weld in a piece from a LS donor car. The frame piece i picked up was from a Roof car and im having an issue with it lining up properly with my trans crossmember. Here are pics and you can see what issue im having. If you look closely the holes for the crossmember are not in place as they need to be. I lined up the Frame piece with where the spot welds were and how it was routed on the LS roof car floor board.

IF someone can take pics of their underside i would appreciate it highly
