Thank you, Gdads51. That article still didn’t say what differentials are best to interchange. It just references swapping a 1955 thru 1958 pumpkin…..whic is very hard to find. Aren’t there other options? Can a 1955 thru 1967 differential not interchange?

Also, the shared article says I must change my spring perches if I do the 55-58 pumpkin swap. Why would I need to change my spring perch if I’m using
My original stock differential housing, if I’m just swapping the pumpkin?
