ok so you have the 1350-1344 then right. According to http://www.actionmachineinc.com/ujoi...ringguide.aspx I have a 1350 u joint because of the following measurements

Outside Snap Ring U-Joint / End Yoke Chart

Dim. D Dim. E Series
1 1/16" 3 7/32" 1310
1 1/8" 3 7/32" 1310 Special*
1 1/16" 3 5/8" 1330
1 1/8" 3 5/8" 1330 Special*
1 3/16" 3 5/8" 1350 ----------------------------------------------------I have this one
1 3/16" 4 3/16" 1410
1 3/8" 4 3/16" 1480
1 3/8" 4 31/32" 1550


For Dimension E using the end yoke, measure inside the two locating tabs.
*For 1310 & 1330 Special, only 2 caps are 1 1/8" & other 2 caps are 1 1/16" (primarily used on Ford applications
