I have seen u-joints and yokes refered to in different series, like 1450 or 1370 I think. What is the difference in these and how do I know what I have. What would be the best to use??

Thanks.

The numbers are representative of the cap o.d. and trunion width. Larger numbers indicate a bigger joint.

Cardan Joints - Light Vehicle
Spicer Life™ Original Equipment (OE) Cardan Universal Joints
The newest cardan universal joint in the Spicer product line offers advanced design features for longer life and superior performance. Bearing cups are case hardened through a carburizing heat treat process, and the inside diameter and thrust washer surface are machined to the highest tolerances of all Spicer bearing assemblies. The journal cross is cold-formed for added strength, and trunnions are machined to give the best possible surface for the needle roller bearings.

Spicer Life OE cardan universal joints stand above the rest for the tough, worry-free performance demanded by today's discriminating consumer and are the preferred choice of many automotive design engineers for passenger cars, pickup trucks and sport utility vehicles. They also have proven performance and are used extensively by professional motorsport teams in IROC, NASCAR and NHRA.



Cold-Formed Journal Cross
Cold-formed for increased strength, the journal cross is not through drilled with grease channels, but rather partially drilled to increase strength and retain the appropriate amount of premium, lithium-based grease for maintenance-free operation.
Thermo-Plastic Seal Guard
Helps prevent contamination in the bearing assembly and secures the bearing onto the trunnion of the journal cross.
Triple-Lip Seal
Enhances grease retention and prevents contamination in the bearing assembly by utilizing three lips instead of two.
Composite Thrust Washer
Eliminates metal-to-metal contact between the trunnion end and bearing cup. Prevents wear and end galling, and lowers the overall operating temperature of the universal joint.

Whats the biggest yoke you can get for an NP 203?

I am pretty sue you can get the 1410s. If not you can make/have one made. Those should do the trick. Never seen a 1430 or 1480.
