I think that's what B7 blue looks when aged? Could be wrong. I think there are better paint options than B7. But it is what it is what it is. And certainly wouldn't exclude because I like B5 a little better? Lol.
I bought my current GTX after 3 years of looking, 4 years ago. To replace a F8 GTX I had to sell many years ago. And that was the only car that haunted me. Including recurring dreams. Although it's not numbers matching (but period correct) the primary difference is the interior. My first was black bucket with console. This guy is camel tan with split bench and no console to same 4-speed. I didn't think I would like. But have to admit. The camel tan does work well with the F8 green. So never know what will grow on you. A quick walk around vid below.
P.S. The recurring dream of my first GTX loss has ceased. Although same performance package as first? Definitely a different personality. Not quite as quick thru the gears due to taller rear 15" rim tires. But much better and more a highway commando. Awesome high speed stability for a car 50+ years old.
I'm VERY sure Oldmanmopar will be as happy with his find as I'm with mine. Again, GTX is always a good find.
