I'm restomodding a 57 chev pick-up.(stock 350). I'm planning a Volare front clip (I know, I know. It's old school compared to MII kits but it's cheap and easy and suits my budget.) 9" ford rears are scarce as hens teeth around here so I'm thinking the Volare rear, being the same width might be a good one to use but I'm planning to use an OD tranny. I know nothing about Dodge rearends. Are there some good gear ratios out there in wrecker land for these? Does it have a center chunk that easily changes out like my Ford 8"? I understand that 76-80 F body(Volare/Aspen) and 77-89 M body(Diplomat/Gran Fury/Lebaron/New Yorker/5th Ave) are all possible donors (the right width) and I'm wondering what gear ratios they come with. Anyone know the door tag codes for ratios? I'd like something around 3:55 - 3:73.
