i put all new suspension and steering on my 65 mustang. the car has disc brakes.I reused the spindles that were already on the car. when i went to connect the tie rod ends to the spindles i realized that the stud on the tie rod end was too small for the spindle making it loose. the numbers on the spindles are 5D-7-A (PASSENGER SIDE) and 5D-6-A (DRIVERS SIDE). my question is, what did these spindles come off of so i can buy new tie rod ends that fit the spindles?
