Great info, the question now is: Will the pumpking from say a '57 ranchero fit right in the place of my current 8" without having to modify my axle? <---Not sure if this is a dumb question, but even if it is, I wouldn't mind getting an answer and looking dumb ! Of those diff's on the 57-59 ranchero's, did they come with traction-lok or where they open rear's? Thanks!
