my truck is a 45 1.5ton, 12'flatbed,2spd. rear w/hand shifter... I had the wheel cyls. and master sleeved w/stainless steel.One machine shop was in Quincey/Calif., close to me for shipping. I also got some info from Hemmings, and used a machine shop in Lincoln, Neb. I can't find the invoices, and its been over 10yrs. I use silicone brake fluid, don't have a hydro-vac unit. My truck is a work truck. Just hauled 3yrds/1 1/2-crushed rock for my 4x4 driveway.Haul firewood, 3+crds a load. I just crawled under there and adjusted the brakes...everything still free and easy, adjusters/brake shoes etc...If you check with your local machinists, he might be able to do what you want...
