a500 question

Yeah I called the stealer by work because it's more convenient than the closest to home and got some kid Ive never had before, the guy I know apparently left early for the day. Though the kid did tell me that the number I asked for was discontinued in Feb '16.
According to Mopar parts giant the number I was looking for does say it fits the trans from that year make and model that I pulled the trans from
So I'll go with that for now. I did punch in one of the numbers you gave at that site and no dice there. The woman who answered at WIT did say something about another one that went all the way from '60--'89 though but didn't provide any part number either theirs or factory just that the one they show for my year, is backwards compatible. Can't believe all this mess for such a small part
