Another Fender Tag Question From a Newbie

I just received a Galen production option code book the other day that I bought to help research my cars. If I'm reading it correctly the 7 digit for 65 is vehicle sales and delivery mapped to sales codes 650 to 659. If I then look at the sales codes for 65 code 656 (is that how I would map the '6' in digit 7?) states SHOW CAR FINISH "B".
By this same logic, code 9 for digit 3 is mapped to sales code 530 to 539 and 539 states 3-SPEED/VARIABLE WINDSHIELD WIPERS/WASHERS.
The book states that digits 1 and 2 map to sales codes 510 to 529, so I guess your 1 would map to 511 which states MIRROR - OUTSIDE LEFTY MANUAL CHROME.
Does that sound right?

Using that same logic for 65 in the code book, here is what I get for your ABC line.
AB is engine code mapped to sales code 340 to 359 so your 31 is mapped to 273 1-4BBL 235hp 8 CYL 10.5:1 C/R then it has model VBL family LA
C is accessory groups mapped to sales code 320 to 339 so your 2 is mapped to 322. 322 has 2 entries one for safety group chrysler and another for FORMULA S PACKAGE BARRACUDA which has a paragraph below it stating: Includes: Commando 273 V8 4BBL, Rallye Suspension, Firm Ride Shocks, Tachometer, Fast Manual Steering Ratio, Nameplate Frt. End-Formula S, 14" Sports Car Tires, 5,5" Sports Car Wheels, Sports Car Wheel Covers
D is transmission mapped to sales code 360 to 369 so your 3 is mapped to 363 which states TRANSMISSION-4 SPEED model VBLRWPDC family FLR SHIFT
E is heater mapped to sales code 400 to 409 so your 5 is mapped to 405 which states HEATER-FRONT WITH DEFROSTER
F is ? book goes from E to Q +S and then V
Q + S is radio and is mapped to sales codes 441 to 469 so your 1 is 441 RADIO-AM MUSIC MASTER/ECONOMY
V is backup lights and is mapped to 473 which just states backup lights
then under all the abc codes given the book states Other code meanings unknown or unconfirmed

Hope this helps - sounds like a sweet ride!
