There is a great restoration/hot rod shop in Warminster Ontario called Body by Biggs (
www.bodybybiggs.com).
I have had him restore a couple of my cars and he does an excellent job for a reasonable price and I strongly reccomend him. He just finished doing my wife's car, and my stripes were done at the same time. His number is (705)325-0845 if you want him to quote a price.
We used the factory stripes as a template so they would be accurate.
Also, we had the stripes end around the edge of the rear of the hood and trunklid. The factory stripes do not wrap around the edge, and leave an odd looking body coloured stripe near the windshield and back window.
