To request the ASC # and conversion information for your 1998 to 2002 Pontiac Formula or Trans Am WS6, please send your VIN to ws6info@1le.org. A photo of the service parts ID sticker is best, but a typed VIN will work.

I am only providing the data by email, but if your VIN is in the database, you will receive a PDF letter similar to what ASC provided.

Note: I only plan to offer this service until 2030. Unless someone takes it over, access to this data may be limited after that.

I have the VINs and RPOs for every last 1998 to 2002 WS6, however there are gaps in the ASC records. While I have been able to fix a lot of those, there are gaps in model year 2000 that cannot be fixed. We simply will never have the build sequence or date, as the ASC records were lost.
