u- joints
Steve, I wouldn't be afraid to run 7290's with the tires that you are running. I was running 7260's earlier this season but as you know, the diff yoke and rear joint came apart. I am now running a shortened shaft from a 70 Super Bee with Precision 7290 joint in front and a 7290/1350 conversion joint in the rear. If plans go right I will get a new shaft made with 1350 joints front and rear for next year.
