When you know you are not dealing with a mopar person

When they try to tell you the 727 TorqueFlite was weak and they would always blow up (?!?!?!?). Or the Duster wasn't based on the Valiant but its own platform, and A-bodies were narrowed in '67 (this was an older Ford guy at a track event, probably just had his stuff all mixed up). Some people at the track were also asking stuff like "You gonna put coilovers on that thing?" ...No because that would involve swapping the entire front end including the subframe and converting the rear suspension to link-coil type from leaf springs. It's got them TORSION BARS Y'ALL, still got a lot left to do with the factory suspension before I look at doing big expensive conversions to make the suspension the same as any other performance car (Boring!). Can't really blame them though, it was a road-racing-style event so all the cars there were late-model imports, Mustangs, Camaros, Corvettes etc. my Duster was by far the oldest thing there.

Those people were all pretty reasonable though, thankfully I haven't run into someone who is a total jackass and adamantly tries to tell me something incorrect about my car or old Mopars in general.
