Its not a Mopar,but....
First: Great find. It's an American Classic.
Second. Stop apologizing. "It's not a MoPar but..". Starting your thread with a weak comment, doesn't bode well for anyone. You bought a Classic and there's nothing demeaning about it.
The Brand Loyalists ( many of whom also own other brands) will moan and grown, but most would be thrilled to own a 55 Nomad. Those who wouldn't, don't.
It's your car, it's your decision, and it a really Awesome buy.
Congratulation!
