I believe that is the correct spindles that followed the KXX spindles. The KXX spindles were used for a short time until they started production on the new spindles.

The KKX marked spindle machined for the Boss 302/Shelby and not the Boss 429 was used first for a very short time as has been mentioned (3/69 4/69 ?) . The OP listed D0AZ 3108  spindle would only be correct on a 6/69 Shelby if it had the all important "B" suffix. That D0AZ 3108- B spindle is the same as Boss 302 . It also takes a special Boss/Shelby Rotor. A common 70 regular Mustang rotor will not work on a Shelby/Boss spindle.That is the reason why many were changed out. The big suspension big bearing spindles were commonly changed out with the regular 70 Mustang/Torino D0AZ 3108 C spindles because the 70 Mustang rotors were common and the tie rod ends were the same larger diameter so the 70 regular Mustang/Torino D0AZ 3108 C spindle easily could be substituted. This typically happened the first time a Big suspension Shelby needed a rotor. The C9 spindle would only work if you changed from the larger tie rod ends to the smaller tie rod ends.You would also use the smaller bearing 68/69 rotor with the C9 spindle.  The Boss spindles are very hard to find. This is all from my time at the Ed Meyer school of "Big Suspension"  ;)

Hi ---on other car early June production I have both DOZA 3108    ----B--- AND KKX on passenger side, to be correct I assume we need to change later to 3107 or would it be wise th change them both to  C suffix if I can find them---thanks

Don't get in too big of a hurry to change them as I have read of some cars having one of each. I'm sure someone with more knowledge will chime in.
