Ended up not using either AutoZone u-joint I bought. I had to buy a 7260/7290 conversion joint from NAPA for the diff side. Then they used a 1310/7260 conversion (from Spicer) on the trans yoke side. The end they cut off and repaired was an odd diameter and they couldn't get it in 7260 anymore. Fun times. Now I have a drive line that no one will know what to do with in the future.
