Dan the Gear Man Tech Notes:
U-Joint Specs
Also Used for Retrofitting
Applications

Tech Note 1: U-Joint Specs
This is a special conversion universal joint used to adapt a driveshaft with a slip yoke made to external snap ring Spicer 1330 specifications to an axle with a pinion yoke made to fit Detroit Universal 7290 series internal c-clip u-joints.
Spicer 1330 external snap ring universal joints have 1-1/16″ diameter cups and have a 3-5/8″ overall width.
Detroit 7290 internal C-clip u-joints have 1-1/8″ diameter cups and fit yokes with an inside measurement of 2-5/8″.

Tech Note 2: Also Used for Retrofitting
The only original equipment use I know of for this special conversion u-joint was by Dodge for the front driveshaft to front axle coupling on early to mid production 1999 full size Ram 4×4 trucks. It can also be used for retrofitting any other Dodge application that requires coupling a 1330 series yoke to a 7290 series yoke such as when replacing the factory slip yoke on 1993-1998 4x4s with QU40701 Slip Yoke.
