Because of the numerous/many possibilities, Dana does not list Drive Shaft Slip Yokes (which would include the dust cap) based on application. To determine/verify the Dust Cap that is required for your 1994 C3500, we will need the OEM part number of the Drive Shaft Slip Yoke itself. To clarify, Dust Cap part number 211121x is used in 19 different Drive Shaft Slip Yoke part numbers, with the largest spline being 1. 390"; therefore, based on what you stated: "It has to go over a 1-inch spline shaft." The 211121x would not work in your situation because it is 3/4 inches wide.

Get this! My factory TJ Rubicon front driveshaft was ripped to shreds. This part fit perfectly and allowed me to keep using the stock shaft without having to worry about water and dirt getting into the slip joint, as well as allowing me to grease the splines in the joint, which I couldn't do with the stock setup.
Everything appears to be fine.
It would have cost a lot of money to replace the drive line boot. This item is fantastic. It would have cost more money and time to replace the drive line boot. The only disadvantage is that if the fitting is damaged by rocks, it can be easily replaced.
Very quick delivery, and the product was exactly what I needed.
I've broken a few of these on the trail, so I keep a few spares on hand. Much better than a boot in terms of functionality.
It went off without a hitch. So far, everything has gone well. If anything changes, I'll update this post.
