Hello guys, Is there an expert on differential Yokes? Need to replace mine on a '02 3500 single cab and chassis. 5 sp. diesel, 2 wheel drive. My yoke is a spicer and has "C3-4-2019" on the curve by the nut. I was offered one from an '01 Dana 80, Spicer and "SD80" stamped on the curve. Anyone know if these will interchange??

How do I Id my differential? I don't know what kind of rear end or the gear ratio is in this truck. Any help? Thanks, Joe.

 

If it is a dually, it will have a Dana 80. There are two different choices of yokes available, and you will be able to tell the difference by visually comparing them. The dust shield around the seal area is the biggest difference.
