Thanks for verifying, I thought the flexplate was useable for all Chrysler auto trannys. The 998 is substantially stronger than a 904 though.

The flexplate worked just fine. There are two sets of holes. The 904/998 uses the inner ones, the 727 the outer ones. ============================================================= Posted by wixList Archiver -- http://www.amxfiles.com/wixlist
