If its a 4 speed sure ain't a 6-14. Yes could be deluxe 66 as well. If the 6 is reversed motor to 30 - 32 6's (exhaust drivers side pre 30's L 15 motor)you got a 29 probably. Could be another wrong year registration based on sale.
The car was incorrectly listed a a 614 back when he submitted the pictures ten years ago. I later corrected the mistake, but the people who host this website had a server crash and had to restore everything from a backup that was not current. My corrections were erased and stayed that way until I recently learned of the error, so now I corrected it again. Either way the car will need a lot of work.
