Go to the B&M parent website, look for downloads and download the catalog (PDF) Looks to me like you have the wrong flexplate--------on the other hand it doesn't look like they show the "right" one Footnote 2, by the way, is "8 bolt crank"
"A clue" is that they list TWO plates for a 360.....one with 904, the other with 727. both of them have bolt patterns for 10" converter...........
