2.  Could not be purchased with a 350 c.i. engine
3.  Did not have a separate VIN identification (used the GS455 VIN identification).

12. Came with a slightly largerl trunk tension bar to support the spoiler.
13. Was a mid year car produced between the months of February and June.  The three digit number on the trim (cowl) tag below the TR and PNT is the month and week the body was made by fisher. (EX 04D would be fourth month fourth week). Most cars were produced at Buick within a two to three week window after the body was created.

15. From the information gathered through the GSX registry VIN numbers range from approx. 446370H120000 to 446370H335000.  Some of the VIN numbers are within 30 of each other but most of them are stand alone numbers.

ST 70 44637FL1 175000 BDY to ST 70 44637FL1 288000 BDY.  Some of these numbers are consecutive and seem to be in groups of 20 to 40 but with the few cars that are in the registry it is very difficult to get exact.

Items to look for to help determine if it is a real 1970 GSX or not.

1. Paperwork is always the first option.  Ask the owner for original bill of sale, Protect-o-plate, body production sheet (usually found on the gas tank), Broadcast sheet (usually found in the drivers side pillar tucked up under the dash pad), or any other identifying paperwork.
2. The stripes down the side of the car had a small miss match directly above the rear wheel well.

4. There is one weep hole in the rear spoiler.
5. There are holes cut into the trunk lid to place the bolts for the rear spoiler.
6. There are holes drilled in the front part of the frame to mount the front spoiler.
7. There is and X stamped into the support plate of the Sports mirrors.
8. The body plate on the Cowl should have exterior paint as either Q-Q for Saturn Yellow or 10-10 for Apollo White.  The Saturn Yellow color is unique to this car the Apollo White is not.
9. There should be a 3 inch hole for the hood tach or have a hood tach.
10.  The dash pad emblem says GSX.
12. There is a quarter panel decal on each side of the car.
