1967 dodge dart 383 gss or gts

Yep 65Val nailed it. Started around April but not many dealers advertised the package until the 1968 production year. The GSS was only for 1968 where Dodge ordered 48 383 GTSs to be converted to 440 GSS cars for Grand Spaulding Dodge. The 1968 440 GTS/GSS cars were all true "M" codes too! They were shipped to Hurst without engine. At Hurst, the 440 was dropped in, the battery was located in the trunk, and the car "finished" before being shipped to the corner of Grand and Spaulding in Chicago
