Does anybody know the best place (cheapest) to buy these from. I'm wanting them for my 67. thanks

I got mine from Summit when they had a 10% discount. I think Jegs and Summit were the same price before the discount. I had to have an adjustable upper arm when I fabbed the Dana 60 into my 66. They are the best quality with the trickest bushing set up....good choice!

If you don't have a pinion angle problem, I'd stick with stock uppers. The adjustable uppers really don't offer any advantages other than being able to easily adjust your pinion angle.

If your pinion angle is OK, I'd spend the money elsewhere.
