My local NAPA only has parts listing for trucks up to a 3800. Mine is a 56' 4400. Are the wheel cylinders and HydroVac the same on the 4400 as the 3800? Also, does anyone have any problems with Wagner brake parts or should I stay with Raybestos or even look for something different?

Thanks for your help and advice.
