Should a Kaiser be allowed at a Mopar show?

Really depends on the group. Sunbeam's are usually not allowed and Chrysler owned the company from 1964-81(I think) I know it would be odd to be at a mopar show in your ford powered Tiger with a pentastar emblem on it.
Case by case basis. No fiats, no simcas, no Renault. A Tiger is okay, if it's got a 340 or 273 in it. Lol.
