Not Mopar but followed me home anyway-----

If I member right '65 and previous SBFs had 5 bolts at the bell housing mounting. '66 and later were 6 bolts. 302s started in '68. 260s ended in '64. '67 was the last year for the 289. If it has a top loader T&C 4spd, you can put a Hemi in front of it and not hurt it.
