Forgot to say, a clear copy of the 1970 CAR BUILDING ORDER form is reprinted in Eric White's excellent Identification Guide book.

Slight difference from your '71 revision. I do see where your Copy shows SPRING and under that REAR and under that RH. & LH. boxes. The '70 Form did not drill down to specific RH & LH boxes. Same for SPRING FRONT.

Eric's version is the same as used for that "BUILD LESS STRIPES" '70 Judge.

Otherwise you should be able to decipher many headings from the copy in Eric's book.

From what I see in the pic you posted, the car has:

Axle Ratio 37G: 3.23 ratio, diff type (locking or open) indicated elsewhere
Tire Code PR: G70x14 Fiberglass Belted, Whitewall
Sales Code 403: AM-FM mono Radio with windshield antenna
Sales Code 424: Spare Tire & Wheel Cover
Sales Code 431: Console (available w/ Bucket Seats Only)
Sales Code 451: Custom Seat Belts - Frt. & Rr. w/ Frt. Shoulder Straps
Sales Code 474: Rally II Wheels
Sales Code 491: Wheel Opening Moldings
Sales Code 503: Power Steering (501) and Power Front Disc Brakes (502)
Sales Code 532: Soft Ray Glass, Windshield Only
Sales Code 582: Custom Air Conditioning
Sales Code 602: Endura Styling (not extra cost on 4200 GTO)
Sales Code 712: Safeguard Speedometer
Sales Code 742: Unknown, might identify specific badging by Model, 742 could be GTO badging but that is just a guess. Not an extra cost option appearing on the Invoice or Window Sticker to my knowledge.

Hope that helps.
