newbe just picked up a 65 dart gt covertable this week!!!
I thought there was some special package with the stripe. I've seen two others done the same way. I have an originally white with black interior/black top 273ci 65 also. Yours looks to be in about the same shape as mine when I got it. Good luck, and if you go looking for parts let em know I may have already been down the same road.
