From the Original Microfiche Plates (North America), dated 1989: 025 906 022 Vanagon 2.1 2wd & Syncro 86-Early 89 (To Vin 25-K-075000) 025 906 022D Vanagon 2.1 2wd & Syncro Late 89-91 (Fr Vin 25-K-075001) Later on, Volkswagen superseded the 025 906 022 to the 025 906 022D as a replacement. I do not have info on models outside North America. As noted in previous posts "X" following the part number and/or letter suffix designates the unit as "Rebuilt" -- Jim Thompson 84 Westfalia 2.1 "Ole Putt" 73 K Ghia Coupe "Denise" 72 411 Station Wagon "Pug" oldvolkshome@gmail.com http://www.oldvolkshome.com ********************************** On 11/10/05, Warner, Jeffrey (Jeff) S (J6C) <Jeff.Warner@dla.mil> wrote: > > Okay, now I find myself replying to my own post.
