Definitely want a set of the rear diffusers for my roadster. Called all the Chrysler/Mopar/internet parts dealers/wholesalers that still list the diffusers and none are to be found since they are dicsontinued (yet none will remove them from their websites - go figure!). The aftermarket ones (on E-bay) in fiberglass are less than perfect and unless you are comfortable doing some modification (or gel-coat work) they are not worth the price they are asking. Checked the SRT-6 website and they talk about a group buy in carbon fiber, but was unable to add my name to the prospective buyer list and can not find any updates for the past couple months. While I have worked in fiberglass for years, I doubt it will be cost effective to produce these at a reasonable price. Anyone have any suggestions?
