Disc Brake Upgrade Reference Thread

from what I have read the 73-87 crossmember requires drilling even on a 63-67 so this means it bolts up different on that frame also. seems to me that the frame on any 60-67 should be the same. so a 63-67 crossmember should bolt straight on??? can anyone confirm?

The 60-62 frames are the 'X' frames and completely different. The 63-66 x-member will bolt up, but so will the 73+ that has all the disc parts already attached.

To be more specific, the extra 'drilling' required when swapping a 73-up c.member into a 63-72 frame is 2-holes. The holes aren't 100% aligned between the different c.members requiring the drill to 'stretch' the holes slightly.
