thank you
My answer is "Neither." I'd return the one that doesn't match and get the proper flexplate or stall converter. You're dealing with critical, rotating equipment that's going to amplify any tiny differences into vibrations, which lead to cracking, which leads to failure. Just my $0.02 and others may disagree.
