What are the most likely Donor vehicles for the A 500 4 speed automatic?

V6 & V8 Dakotas.. I actually have two sitting here, one is the early RH type the other is the later RE type... But the RE's have redesigned planetaries that are supposed to be stronger so I'll be using those in the earlier trans.... I actually picked up three including a 518 RH from a metal recyling yard.. $50 each...
