I've been searching the forum and online, but I haven't quite nailed this down yet. I need to buy a flexplate for my Buick V6 odd-fire (Casting 1381623) to mount up to a TH350 auto tranny I have. The tranny has the BOP housing, matching the engine. I can't find the part on Rock Auto (searching under Jeepsters). Also, are there specific bolts I should buy at the same time? I see that partsmike.com has the odd-fire flexplate, which I'm sure would be the right part, but it seems like I could find a better price than $90. Or is that the going rate? Thanks.
