Back when my 65 was a daily driver, I had a problem with the rear tires wearing on the inside. Took it to a body/frame shop, they initially said that a PO was probably hit on the side, tweaking the diff tubes a little bit. When they started measuring, they found that the housing had somehow bent slightly, just enough to cause the tire wear but not affect operation. Their solution was to chain down the ends and jack up the center section until the flanges were parallel. Drove it fine for another 5 years before I took it off the road. My question for you guys is should I waste resources building this rear (want to go posi), or should I just buy a new one from Currie or somebody like that? I was thinking of going with a 9", but not sure it's necessary. I'm probably going to shoot for around 400 hp with the engine, thinking I could get a strong center section for the 8" to handle that with no problems. Thoughts?
