.......used actual measurements of bearings ID...OD....thcikenss...seal or not.... and did their searches using the found values...... it would spit out what was available by "makers" and further searches gave us a location and delivery time and price....... the ND 928 were always elusive and usually OLD stock.....

Personnaly I have reverted to buying old rolling frames or just the front axle for parts..... took me 4 front axle to find a replacement R-Zeppa U joint and now have some spare 928 resting peace deep in a jar of engine oil.....


TIP....for future restorers...... R-Zeppa are more common on Fords but remember that GM axles were used on Ford during part shortages. ....and before dropping lots of cold cash ask the seller if he will allow you too remove the hub caps for inspection...only 3 large screws..... in the very center of the stub axle where the big wheel nut is attached look for a small hole about 1/4 inch, do not be mislead by the centering tool shallow recess used to machine the stub axle..... try inserting a slender steel rod...... should go in 3 ichnes + or _ and the hole should have machined threads...... and old dental pick is nice to carry with you. The reason for the threaded hole is that there is a screw at the very bottom that hold the R-Zeppa u-joint into the steering cup.... without it it is just a regular mass produced U-Joint.......
R-Zeppa came in two sizes.... one for the C15a and a largersize for the C60
....they were also used on.
Some early DODGE 4x4 used them but not sure if they are interchangeable....
....and you will need a FORD shop manual as it is the only one that carries details of the R-Zeppa Joint.
