bolt patterns

[67 GTX]

Does a 1963 Chrysler have the same bolt pattern as later 60's B-body cars?
And do the brake drums swap over?

i do believe the 63 b body has the large bolt pattern. and should swap out just fine.

That was sort of a throwback from when wheels were held on by a single large nut instead of several (think 60's Corvette knock off wheels). The left side had lh threads to make sure the wheel rotation wouldn't un-thread the fastener. That mentality was continued over when regular bolt on wheels came into use, until finally someone realized that it wasn't needed. After all, Ford wheels weren't falling off, so....
