Hi glad to be a part of the group. My grand father gave me his 45 Dodge truck when i was 14. Now nearly 50 years later im building it like i want to.
So it sounds like you have a Magnum Block? Not an LA?
Your post stating "Looking in the years 67 to 92." makes it seem you need the early plate which are available.. The Magnum plate seems to be out of production so you would need a used one...
Sounds like a cool truck, you should post a few pictures...
