I have seen power disc brake kits for 1/2 ton trucks with 5,6 lug wheels. Does anyone make a kit for 8 lug trucks like 3/4,and 1 tons? I have a 59 3800 with 8 lug wheels that i would love to change to power disc. Do late model 3/4 ton chevys (c-20,30) brake parts cross to the 50's trucks at all? Does anyone make a kit to use these 70"s-80"s brake and axle parts for conversion to 50's trucks?? also the truck has 17.5" wheels and tires. Will later model (c-20,30) 8 lug wheels be the same pattern, so i can get some radial tires. Oh yea one last thing, this truck has a 9 foot stepside bed, does anybody know who sells parts for a 9 foot bed, (wood, metal bed strips etc) thanks everyone
