There was a mid year change on the driveshaft. From 60 to early 64, they use 3 regular u-joints & the center support. I'm not sure what the later style uses. I believe there is one or more sources listed here for the center support. I believe it is "The Damper Doctor" as well as one or two others that carry these.
