68 GTS 383 with PB & PS

Dodge/Plymouth started installing B Engine-383's into A Body's in '67. '69 brought out the RB Engine-440 into A Body's. Everyone knows when the 426's were installed? And by who? We had one '68 426 Hemi Dart in my hometown, just outside the Motor City. Street Legal, sort of. Hey, it did have a License Plate.
