A body cop cars

according to this site mopar had taxi and cop car package on valiants starting with 1975 model years, and though it does't state, probably sold them until a-bodies were replaced by the aspen/diplomat format.
i remember seeing picture of a 67-69 valiant police car used by some swiss or dutch municpality, but it was probably just a stocker with cop paint and equipment installed for the department after purchase.
