My solution was to contact Meziere directly. They had me send my flexplate back to them and drilled the new plate to match my SC convertor. They also rebalanced it to the stock SC specs. They obviously knew my situation which makes me wonder why they dont have both convertor patterns already drilled and two seperate plates, one for NA and one for SC engine. Between discussing it with them, sending my plate in, them performing the work, and getting it back, it took about a month. I also had to come up with a solution for the crank bolts that wouldnt have heads so thick that they touched the back of the convertor AND were long enough to make me happy. All in all it was a bit of a learning curv but the trade off is that they performed the work and sent it back to me for free.
