I have heard and searched that mid 70's nova diffs are great in width compared to the stock diff of a 53 half ton. I guess a 75 is as mid 70's as you can get. I have found a 75 nova diff with good brakes and 3:73 gears and the stock nova springs. I haven't decided what tranny I'm gonna use yet, but is this something worthwhile for when the time comes? What needs to be done with the springs/perches? Who has swapped to a mid 70's nova diff? Thanks Much!
