1980s Donruss pack pulled signifier?

Is there a way to tell if a card is pack pulled or factory set pulled? I know 1987 has a back-orientation clue, but wondering about the other sets. Many thanks!

Yes, 1985 and later have slightly rounded (or "pinched") corners.
Factory Set cut slightly smaller.
Kiss me twice.....let's party.
Probably 1983 and 1984 as well.
For 1982, I have seen cards from factory sets with a "rough cut" similar to OPC cards from the same era.
