I was fortunate enough to locate a set of non-retracting Hamill Deluxe Front Seat Belts with 1966 tags for my Camaro (exactly the right combination as the car was built early in the run, first week of Nov. '66, apparently before they started using retractors).

Anyway, they will need a minor cleaning and to have the webbing dyed from blue to black. I've researched this a little, and so far it looks like washing them in the top rack of the dishwasher, and using a spray on dye seem to be the leadiing ideas. Has anyone done this? Any specific tips would be appreciated, such as do you use any soap in the dishwasher cycle, and, any particular brand of dye? Or, are there netter ways to accomplish this?

Thanks!
