It is definitely not an FMX as FMXs were not made until 1968.
Most likely a Cruiso.
If a Cruiso, just swap in a 1967 valve body to get the "standardized" shift pattern that all U.S. makers went to in 1967.
If perchance it is a T35 (and most Studs came with Cruisos), I have no clue whether swapping valve bodies is possible.
