1968/69 Factory Dart 340 Swinger hood
The hood will work on 67, 68, and 69 Darts but the bracing underneath on a 69 has small crumple zones and was drilled for the DODGE emblem for the 69 340 Swinger. There were no drill areas on a 68 since it was GTS only and the letters were directly in the middle at the front like a 69 GTS. Here is an old post of a true 68 hood.
