I own a small Mopar restoration shop called redline restorations. I have restored many vinyl top equipt cars in the past. What I do is, pull of the old vinyl, I use a DA with 80 grit paper on it. Not only will that remove the old glue, but it will prepare the roof for the next step. Then , I coat the roof with a couple good coats of epoxy primer to seal it and prevent any future rust issues. Then I will paint the roof the color of the car (the last one I did was my FE5 70 340 swinger) then install the new vinyl. As for the window gaskets, Yearone has then listed as #WS303 for the rear @ $128.00 and the front as #WCRD690 @ $76.00. Their catalog shows them for 68/69 barracuda's, but I believe 67 is the same. Hope this helps.
