Default '81 U Joints

Looking to replace all the U Joints in my '81 with non Greaseable Spicer.
Checking to see if correct sizes?? Half shafts are 3"
Are the following correct?
Driveshaft U Joint: 5-1310X
3" Half Shafts: 5-1350X
I've heard some say that the Half Shafts U Joints are 5-1330X and some say 5-1350X.
The last thing that I want to do is order the wrong size and have to ship back and wait for correct size.
Looking at buying from Drivetrain America. Has anyone used them before?
Thx

VTech said half shaft in 81 Auto is 1350.
This chart shows 1330.
Will both the 1330 and 1350 fit?
