I know that John Dorgan is now offering a white base gasket, however, I have no idea of cost. I just measured the Ful-Vue lights because I am going to be needing gasket material for them, and found that they each use 34" of material based on a 2" fudge factor. It is going to take 11' of gasket material to do my lights, plus some more for the Federal 184. I wonder how much comes on a roll, since with 3 cars, I know that I am going to be needing a lot.
