Pete, thats a good deal for someone. Regarding using it in a 63, I have been told the base of a 64 wheel is a different size than that of the 63. Not sure if you could change the 63 part the wheel fits to onto the 63 to then use a 63 wheel or not. Im pretty sure the internal bits that hold the 63 together are 63 only and they were a major pita to deal with, I believe the 64 is much improved.
