I have a 52 chevrolet 3600. I was going to replace the master cylinder and wheel cylinders. The 3/4 ton 52 parts are almost double the cost a lot of places then the same truck of different years. Why is this? If Im not going to tow anything. Will the half ton parts bolt up or is this a terrible idea? I only need this to work for a short time a year or so. Until I get the truck into my garage to tear it apart to start the resto.
