The issue is they are about half an inch shy of meeting the holes in the flexplate all the way around... That's why I was wondering if the diameter was an issue? What I mean is if I measured a half inch directly above my holes and drilled holes it looks like it would bolt up? Like I said earlier they are on a smaller diameter measurement. I'd like to keep my stock flexplate... I'm wondering if I even have the right converter. I'll post more when I get it out to compare.
