I have an '82 450T Hawk that I am finishing up. I think this bike came to me with the wrong handlebars-AKA cables and brake line are too tight. I want to buy replacement (7/8" dia) bars that are as close to stock dimensions as possible- but- I don't know what those dimensions are. I need dimensions for OAL, center spacing, pullback, inside rise, end rise. Let me know if you can help. Thanks!
