Hey everyone! So i have some great news! After an epic search I have located a 57-59 Ranchero rear end!!!!! Based on all the info that I've gathered, everything seems to point towards it being the Ranchero rear.... I paid an arm and a leg for it ($400) but it's $ well spent i guess. I looked at the site that 406Rich put up and it seems like the rear end i got is a 57 because of the smooth back, rear facing breather, and the line along top. What do you guys think? Here's some pics of everything except the 3rd member.
