Like many “Cobra” subjects, hubs is not a real straight forward one.
CSX2601 and CSX2602 (Daytona Coupes) dropped the splines as did 427 Cobras. "42 mm splines" returned for 289 Sports.
There were street car splined hubs, street car rear splined hubs in a stronger alloy, street car splined hubs converted to pin drive, race car hubs with splines drilled only for six pins, race car rear hubs made of a stronger alloy splined but drilled only for pin drive, 427 Cobra hubs short and long, and 289 Sports hubs that were splined.
Front hub forgings could be machined into just about anything. Rear hub blanks could be machined into almost anything. They all used the same center lock nut thread system.
I have used samples of most and new old stock of one of the rear street Cobra versions. When I started studying front hubs I was quite surprised that Cobra, 427 Cobra, and 289 Sports were all done differently and are not by themselves bolt off bolt on interchangeable. Rear hubs also don’t exactly interchange between Cobras and 427 Cobras. I have a rear 289 Sports hub but I have yet to by feature and dimensionally compared it to Cobra and 427 Cobra versions.
