Sorry guys, I lost track of this thread. I created this checklist some time ago for those that have asked me about getting a reproduction window sticker, what information is on it, and what it all means.
Eric: Yes, compiling all this info would be a good idea. Publishing is another story. Richard Clark has asked me if I would consider getting all of this together in one place so that he could look it over. Pete Hoffman has asked if I would consider getting him some of this info for the new book he is working on....
I have thought about starting a thread to ask all board members to PM me data about their car (year, model, hard top, t-top, or astroroof, last six of VIN, body #, seq. build #, date of mfg, etc) but don't know how this would go over. I probably should PM SGRIM first and review it with him.
Here are the steps to getting a window sticker. The information below is mainly tailored to the '87 models. The '86 window sticker is slightly different in the gas mileage information window.
1. You will need a copy of the dealer invoice. Do you know the dealer who originally sold the car? If so, contact the dealer to see if they can provide you with a copy of the dealer invoice. If the dealer is no longer in business or didn’t keep the records, there is a solution. Contact Stacy at GM media archives for a copy of the dealer invoice. Phone # is 734.421.0273 x107. The invoice has the base cost of car, options, codes/descriptions/associated costs, destination charge, dealer name and address, dealer code #, and car order #. Cost is $50.00. Once you give her your VIN, she will look it up from the microfiche archives and forward a copy in PDF format via e-mail.
2. You will need the sequential build # for your car. This number is located on the RPO sticker on the trunk lid. The top line of the sticker has the VIN, sequential build #, and “J47”. If your sticker is damaged or missing, you will then have to research the last six digits of your VIN to that of another turbo Regal and pick a number accordingly. For the '86 cars, the sequential build # did not appear on the early build car's RPO sticker (those with the laminated RPO sticker). It only appeared on those '86 cars made from June '86 and later.
3. You will need to determine what ramp code (bottom right of sticker, big block letters) was used on the original sticker. Most 86-87 GNs had a ramp code “PP”. Although I have seen “AT, “JC”, “LF”, and “WX” ramp codes as well.
4. Original window stickers had the text “SOS=6” at the end of the line of text containing the “Final Assembly Point:”. The “=” symbol was in vertical alignment with the last digit of the dealer # on the line above. I do not know what “SOS=6” means.
5. Original window stickers had the text “Part No. xxxxxxxx” below the line under the ramp code. I have been able to assemble this list of GM part numbers for the window sticker form used for the Buick Regals including Grand Nationals, T-Types, Turbo-T's (WE4), and turbo Limiteds.
1984 GN part # 22520821 (from sample window sticker on file)
1985 GN part #
1986 GN part # 22529152 (from my posted inquiry on TurboBuick.com)
1987 GN part # 22535271 regular production August '86 through July '86 (from my files of window sticker images)
1987 GN part # 22529152 extended production August '87 through December '87 (not sure of exact source -'07 GS Nats, Englishtown Buick Performance weekend, or Kirban Reunion)
Please keep in mind that the part # is like a GM trademark and may not be able to be printed on your reproduction window sticker
6. E-mail Triple A Enterprises (tripleaent@aol.com). Point of contact is Bill. His website is
Window Sticker Reproductions for Corvette, Chevrolet, Dodge, Oldsmobile, Plymouth, Pontiac, Buick, and Cadilac . Cost was $35.00 and a couple of bucks more to have it laminated. Size is about 10” x 12”. Forward a copy of the dealer invoice to Bill at Triple A together with the listing of the RPO codes from your trunk label, build #, and ramp code. Ask him to include the “SOS=6” text and if he will include the appropriate “part #” on your copy. While he only communicates via email he is very responsive.
7. When you receive your reproduction window sticker (WS), take it to a copy center like Kinkos and have them scan the WS to a PDF file for you. Now you have an electronic backup in case something happens to the one in your hand. Also, make a few copies for display with your car and then maybe have the WS laminated. If you buy it from Bill at TripleA Ent. already laminated, you cannot scan it to make a backup copy.
