Wow, just saw this. Steve, unbelievable and so close to the house. Glad you are ok. That was was one beautiful Mopar, for sure. I wish you the best on the rebuild!
I'm trying to research these cars myself. There doesn't seem to be any one decoder out there, but I'll take a stab at it:
Top Row:
b 4 = Bucket Seats
Middle Row:
AB 32 = 273cid 4bbl
C 5 = auto trans
D 9 = Front Disk brakes
E 1 = Air Cleaner Package
F 7 = Formula S
H 1 = ?
R 1 = AM Radio...
