No dumb questions here. A bodies have a 5 bolt with a 4'' bolt circle like your 65.
That was from the early 60's to 1973 when they went to disc brakes that shared with the B bodies of that date.
5 on 4 1/2 bolt circle .
Chrysler also did disc brakes from around 1967 to 72 in small bolt pattern.
Now after 1973 A bodies that still had drum brakes had small bolt pattern till 1976.76 being the last year for the A body.
