Now I feel a lot better! I've got to thank you all again. A while back I picked up a 76 with a blown engine for $200 and was going to transfer the P/Steering and piece together the brakes onto the 64. The more I looked at it the more I was thinking that the whole subframe should be swappable! Seems like I was on the right track now after reading your thread. So I should be able to order a set of the 6 lug disc to match my rear end, well the truck's rear end.
