sr88, check the post I made on 12-14-'01:
Painless and cheap front discs for \'60?-\'66 You'll find all you want. I don't know about the '72 front end, but I do know the front from '73 to '87 will bolt right in. On my '64, I opted to use just the spindles, bc the 73-87 frame is thicker, and the motor mounts would stick up almost 2" higher than they need to. I got the l&r spindles from a junkyard for $70. The '72 axles themselves will slide right into your orig '64 housing, and then you'll have 5 lugs all around.
Hope I helped!
