how far back was awhile? i posted it on the tech archives, but nobody showed interest. now for the actual info:
-THESE DRUMS WILL WORK FINE WITH ORIGINAL BRAKE EQUIPMENT, SHOES AND ALL.
-THEY MAY NEED SOME SHIMS TO SPACE THEM OUT FROM THE BACK PLATE
-SHIMS TO INCREASE DIAMETER OF SPINDLE WILL BE REQUIRED, I WILL NOT PROVIDE MEASUREMENTS, AS THEY MUST BE FINE, DOWN TO THE THOUSANDTH
-THE SPINDLE SHIMS MUST BE VERY SMOOTH AS TO PREVENT SEAL WEAR
-THE SPINDLE MUST BE SHORTENED TO PROVIDE FOR THE NEW CAP AND NARROWER DRUM(S)
-DRUMS ARE AVAILABLE AT:

FYI: THESE DRUMS MAY BE SLIGHTLY OUT OF ROUND, YOU MAY COMPENSATE IN ADJUSTMENT AND LIVE WITH IT, OR YOU CAN HAVE THEM RE-MACHINED.
I WILL TAKE PICS NEXT TIME I REMOVE A WHEEL.
