Anyone know if the 700R4 flexplate/tc cover for a 6.2/6.5 is unique?

I need one for my 700r4 that I'm using with a 6.5. I can find plenty of used ones that were with 350s or 4.3s - I got one from a 4.3 S10 4wd and it wasn't even close.

Do I need to hunt one down from a 6.2, or would one from a 350 or 4.3 (2wd) work?

Thanks.

Joe.
