Guy is hinting? this was a hemi or 440-6/ 69 1/2?

If it was a '69 1/2 440 6bbl car, the V.I.N. would be RM21M9.
If it was a '69 Hemi car, it would be RM21J9.
All '69 1/2 A12 cars (automatic or 4 speed) had a 4:10 sure grip Dana 60 and 3'' drum brakes all around with the fiberglass hood and scoop, and 15'' black plain steel wheels with chrome lug nuts and no hubcaps.
Hemi cars if ordered with a 4 speed automatically had a 3:54 Dana and 18 spline transmissions.
Automatic Hemi cars would have had an 8 3/4 rear end unless an upgrade was ordered.
All '69 Hemi cars came automatically with a fresh air hood. (Air Grabber, Coyote Duster, Ramcharger)
All Dana 60 rear ends regardless of ratio were sure grips as well.
Only Super Bees and Road Runners for '69 1/2 were available with the 440 6 pack or 440 6 bbl engine package.
No Six Pack/6 bbl R/Ts or GTXs were built until 1970.
