I found all but 6 RPO codes on my build sheet for my 1986 Grand Prix. The codes are P37, STE, T1H, 7NU, 8TU, 9TU. If anybody knows what these codes mean please post or email the description to me. Thanks for any info.
Did you ever find what was the RPO code P37? I know STE meant build in St. Therese, and the last three were suspension items, but I've never figured out what P37 was.
Sorry, but I don't have access to specific RPO codes for the 1986 Pontiac Grand Prix. However, I can tell you that RPO codes, or Regular Production Option codes, are codes assigned by General Motors to identify specific equipment or options that were available for a particular vehicle model and year. These codes can often be found on a build sheet or window sticker and can be used to determine the specific features and options that a particular vehicle is equipped with. It is likely that these codes will be specific to the 1986 Grand Prix and may not be found on other vehicles.
I have a variety of RPO lists from over the years, but none that give what the P37 code on this 1986 GP build sheet would be. In later years, it was once used for certain 17" wheels, but not in '86.
I have a variety of RPO lists, mostly from my Pontiac and GMC sources, but none show P37 shown on this 1987 Grand Prix build sheet. I came across one usage in later years as a call for 17" wheels, but not for the '86 (Chris's car) or this '87 that I'm trying to decode.
