I lucked out & one of the tool makers at work was able to fix the yoke & the local, small town NAPA had the conversion U-joint in stock to go from the 7290 driveshaft yoke to the 1330 8 3/4" yoke. I was really surprised about that.

Now running the 2.94 open till summer & going to swap the 4.10 SG to either 3.55 or 3.73.
