I never knew Dodge made something like this! How cool!!! If you have more photos, I would totally be interested in seeing what this vehicle looks like from different angles! Good luck on your search too.
The model is 1971, but the paint scheme is 1963 - one year only, then they went with a simple stripe.
It has its own page The Big Blue DOG
There are a couple of groups, all about rediculous restoration work of course.
