ok, I have a 64 4000 with the hydrovac brake system. I'm looking for a rebuild kit and I'm having trouble finding the right parts. the brake piston is 1 1/4th and the clutch piston is 1 1/8th. I've searched online and I've found some that look the same but they don't list the bore diameter. I've also been to napa and they haven't been helpful, I went to carquest where some older people work and they found a brake piston but not the clutch side. My question is does anyone know where or what the part numbers are for the clutch and/or brake rebuild kits?
