What did I buy?! Lucky find for a newbie!

Here's the scoop;
I was looking for a vehicle for under 3 grand that would get me around in MT winters and not slide like an ice skate. So, I wanted an older truck, late 70s, something I could work on and not have to pay somebody. Of course, I'm brand new and just learning EVERYTHING about older vehicles, so I put feelers out to my more knowledgeable friends to keep an eye out.
My buddy tells me his friend has a dart for 2 grand, and I said no way. Like I said, I wanted something beastly! Shows what I know. He made me promise to drive it before putting money on anything else.
So, I did. Turns out it wasn't a dart... close enough. She's a 74 Valiant. And in five minutes with her I was in love. Great condition mechanically, almost perfect, and all stock. Like she came from the factory. Which she did, everything is original, and she has 61000 original miles. She needs some body work, but I get to learn how to do it all myself and I can't wait!
In researching what I got I can't seem to find anything exactly like her. She's got the A38 pursuit package, the engine is a 318, and the transmission is an NP833 three speed on the floor. In all my digging I only found one other like it. Am I not looking hard enough or did I buy something that's a bit unique?
