I have the yoke shaft from the donar truck and went to put the 447 ujoint on and the cap size is correct but the yoke is too wide. Went back to napa and they said they don't have anything else that size. Anyone else have this happen. Only thing left to complete the swap. Btw it's a 2wd

If you're referring to the slip-yoke on the 4L80-E it should be a 1350 joint. Half ton truck driveline should be 3R, but I don't know what year truck you have. There is a conversion joint to go between 3R and 1350 but it's not available with a solid center.

Yes the slip yoke. The best I can tell the donar truck had a 1410 slip yoke. So I kept the 447 u-joint and ordered a slip yoke in 1350. I will find out when it shows up if my research is correct.
