68 Dart GTS

Is there an easy way to tell if a gts dart is a real 4-speed gts big block car. Thanks

Fender tag, VIN (engine only), torque plates, welded pivot ball support on the frame side. Match the VON on the fender tag to the rad support and trunk lip numbers. Match them to the VIN with the broadcast sheet. Without all the support numbers and docs you can't be sure.
