This is what I believe @Duane calls the "Fisher Body Cheat Sheet" - No VIN (434671HXXXXXX) but I assume it would’ve had 439 written on the saddlebag (daily sequence #?) & the following options: M38 - TH350 A51/D55 - Buckets/Console A02 - Tinted windshield (only) U80 - Rear Speaker D33 - Remote chrome outside rear view mirror B50 - ? (Have to check that one) I assume 155 (pearl white split fold bench) was the orig. interior designated and the so the SCO would've been for pearl white buckets & is why that "155" is written in black - Both look to be written by the same person. All I have is a copy of this. There were apparently 2 of them in my '71 GS Convertible (Flint built) & I got this copy of them w/my car but I guess the originals got thrown away by "the girls" who were "restoring" it. The options on #423 match my car exactly. Here's a question: SCO 699 sounds familiar to me and I've seen a few '71-2 bucket seat Convertibles. Does anyone know if they assigned SCO #s by car or by option? In other words, is it possible that all bucket/console Convertibles were assigned 699? Then say a car got buckets/console & a hood tach that'd be a different SCO # or did each SCO car get assigned a specific #? Any idea what the circled A & E are? Top colors?
Dano, Yes they are the Flint “Fisher Body cheat sheets” SCO means Special Car Order, therefore if a car had some type of a special or not recommended option, the car was designated as an SCO car and the number was generated. If you find the POBF or POCP buildsheet, it will list the SCO number at the bottom, as well as the option number/description that is associated with that number. Each car would have it’s own SCO number, regardless of which option created it. The basic reason they did this was to make sure they got paid for the vehicle. I believe the customers had to completely pay for the vehicle or get pretty close, before GM would build it. They did not want to get stuck with a car they could not sell. The number at the top left was the model number, not the vin. That is why it is very hard to verify these sheets for a particular car, as all the seats were the same, and they often threw the wrong set of seats in a car, like they did with the gas tanks. If you have the top center number on the driver side saddle bag, then it was the one for your car. That same number was located in other places, but I don’t remember off hand where they were. Maybe crayoned on the driver side brake drums, maybe the wheels, I don’t remember, but would have that in my notes. They also had “month” codes crayoned on the front bumpers. Both my 70 & 71 GSX’s were original front license plate cars, and when I removed the original front plates, both had the month of production crayoned under the plates. Years ago we were taking apart a 70 White GS 350 Coupe, and one of these sheets (for a 70 White GSX) was rolled up in the Body Shop Inspection Sheet for the car. It should not have been there, but managed to make it into the 350 car. Which made sense, as the GS 350 Coupe was white and was probably in the same white “color batch” as some GSX’s. Duane
