Sharp Diplomat there! You bought that from Dave, the "Old Hippie" down in Texas. He used to run a Great MoPar site called MoPar Style. I remember seeing the videos that he made of this car and him driving it... Putting a 4-barrel on it and the air conditioning was working ice cold... I'm sure it's a very nice car it looks like it was well cared for and certainly you bought it from a real decent guy. As you probably know he's got a killer collection of cars and my favorite is his full size. Black B body Dodge Magnum!
At any rate, add some cool wheels on that thing,combined with a very nice color to begin with, and you have yourself a real looker. Enjoy!
