I have one that says 67 Plymouth Hemi GTX 2'n1 Revell Muscle, Not really a model guy it was given me as a gift when I finished my GTX,but I never got started on the model.Is that what you are looking for?
Depends on what it is out of.Same basic trans from Thunderbird to pickups.Also Studebaker cars and trucks.Does it have the silenoid-governor-speedometer gear in it?Sorry no more hijacking
