Unfortunately, Alabama does not issue a title for older vehicles- - - -ownership transfer is by a bill of sale, possibly a notarized one. I was involved recently in the sale of a mid-1960's Plymouth muscle car to a buyer in Australia- - - - -$40K and done by a notarized BOS. You will probably need to check with your local department of motor vehicles to see what they require for getting a title and registration. There are lots of variations from state to state.
Since the earlier 139 tooth flywheel will bolt onto any stovebolt engine regardless of when it was made, the only way to be sure of a good match-up is to count the teeth on the flywheel ring gear.
