1969 Dodge Dart Swinger 340 "P Code" GTS Clone

You have a '69 GTS hood and grille. The rear panel and taillights are '68. You have '69 front fenders with stock rectangular reflectors, with '68 round side markers added. You have '68 rear quarters with '68 round side markers. Round side markers were stock on all '68 Darts, only. No '68-'69 GTS ever had "DODGE" on the hood. It should have a GTS emblem in the center/front of hood. '68 had the GTS badges on the fenders, '69 did not. And you're right, GTS's did not come with bench seats. Basically, you seem to have a hodgepodge of parts!
