Here is a decoder ring I put together for the '67 GS trim tags. Your car originally had tinted glass (all windows), 4-speed transmission with no console, a rear seat speaker, door edge guards, and deluxe seat belts (nice metal buckles). There are many options that can't be determined by the trim tag such as power steering, power brakes, radio type, wheels, etc. The trim tag only indicated the options that Fisher Body needed to know about for their portion of the process (just stuff related to the body shell). The Aqua bucket seats are fairly uncommon. Only 458 of the 10,659 GS 400 hardtops had them (4.3%). The only interior more rare in the GS400 hardtop is the Yellow bucket seat interior with 407 made. Production of the 458 cars with Aqua bucket seats break down like this: 192 Flint 121 Fremont 48 Baltimore 97 Kansas City
Here's a better image of the BNP: ST 67 = Model year 1967 4 = Buick 46 = GS 400 17 = 2 drs hardtop sport coupe FL1 = Flint Michigan 02A = Built in the first week (A) of February (02) 1967 TR 196 = Aqua vinyl trim, bucket seats K2 PAINT = Aquamarine, black vinyl top
Thank you for all the help. Decided to take the car back to it's original color and top. My girlfriend says you guys rock.
That will be a very attractive '67. I look forward to reading updates in the future. Good Luck with your project. Have any photos of the current condition that you can share?
