The casting # I found on the vertical section rising to the upper ball joint is "XKX 2413 SET1" and 2414 on the opposite side. The large spindle dia is 1.375" and the smaller dia for the outer is .850". I would post an image of one side if I could figure out how.

I appreciate the suggestion about finding any 2 piece factory rotor assembly and using the rotor, but all the searching i have done, the replacements are all one piece, and the small spindle diameters. I've tried Raybestos, Baer, most the other aftermarket and must be missing something where to search.

One post on the Mustang Concours site back in 2016 stated that only NPD and Tony D Branda built a batch of replacement rotors, and only 10 remained. They would not reproduce anymore because they sat on shelves too long.

Hey everyone,
New member here but been restoring Mustangs, Shelbys, Cougars, and Cyclones for decades, and have run into an issue with a '69 GT350H and the front rotors. The bearings in the rotors are larger than the 1969 and 1970 rotors listed by O'Reilleys data base.

I have a new set of Raybestos 6016R rotors that are designed for the 1970 GT350 per CJPony parts, and the bearings are too small (inner and outer). The 6006R rotors for 1969 are also too small. We went thru their entire data base using bearing sizes, rotor diameters, hub assembly height, min. thickness, and nothing.

The small diameter bearing race is pressed into a 1.965" outer bore, and the large inner bore is 2.575" dia. In addition, the top of the inner large bearing is pressed .500" down from the bore lip.

There are no casting, stamping numbers, nothing visible on the rotor assemblies to cross reference who built them.

Does anyone know of a currently available replacement rotor that comes as a rotor assembly?

Also, if an assembly is not possible, has anyone pressed the studs out of the assembly and replaced just the rotor and reinstalled the studs? I would like to find a rotor part number if anyone has done this.

Thanks,
Mark
