GM 3r u-joint is the same size as Ford 1330. The difference is Ford uses external retainers and GM uses the circlips on the caps. Most aftermarket 3rd member yokes are going to use 1330 or 1350 joints. There are good YouTube videos out there on how to tell the difference between the 1330 and 1350 u-joints. Keep in mind there were a couple of different 1330 u-joints with 1.060 and 1.125 caps.

All, based on the measurements it appears thes are the 1310 series, its about 3 1/4 length and 1 1/8” diameter. I appreciate the help.
