Working on the 68 Valiant this week..Got a 73 Big Bolt 7 1/4 rear from a member.Drove 400 miles round trip to pick it up.Truck gets 10 MPG. Paid $150 for the rear. Got it home,opened it up and the spider gears were all chewed up.Now I got over $400 in it with bearings,seals and what not.Moral of the story is,,, this is what I get for being cheap instead of putting a 8 3/4 under it in the first place.......Oh well I've made worse decisions........:banghead:
