OK I drove the truck yesterday for the first time with new radial tires ,balanced, on strait rims.Wow what an improvement over the old stuff that had been sitting for probably 30 years in one spot.The Bendix brake upgrade made a huge improvement over the huck system.I highly recomend this update for the brakes short or a disc setup.Thanks once again for everyones input and help.Now I can start building the flatbed.
