Alex,
I'm from Brazil, near Porto Alegre, and only today I saw your brave ádventurous spirit" in restoring your dart, and congratulation is a small word to say for your job, at least !!!
As everybody saida here, keep up with the good work, and clean stuff you've made, my friend !!
Now I bought a 79 Dart, very similar to yours, but mine is a 2-door model, it belonged almost its life to my wife's family, was sold to a museum near here (Ulbra) in 1998, and now I managed to buy it back, only waiting for the judge final settlement to take the car...
You may see some pics of our babe in my profile,ok ?
If you may need something from here just shout, and we'll be pleased to help, huh ???
A big hug from the South of the Border !!!
