Trying to ID the front spindles on my '57 Ford that were changed when they change over to disc brakes,want to replace rotors/pads---Drivers side shows D208AE  76, passenger side D207AE  85, was suggested that D2 stands for 1972--any clues?  Thanks for the help in deciphering the tag on the 4-speed(turns out to be a '77 3-speed with overdrive that's a top loader imposter).
