Hy crockbuyer, It's possible that someone swapped rear axles on your truck, could you post a picture of the wheel cylinder you're looking for? In the pictures in my brake parts catalogs Raybestos p/n WC18010 ($47.81 @ Rock Auto) is the rear wheel cylinder listed for your truck, and the mounting bolts are only very slightly above the centerline of the bleed screw hole. I assume the cylinders you have been recieving will not bolt into place on the backing plate, is that correct?Just in case you want to compare the Napa p/n is UP 18010, you could go to a store which stocks them and have a look.
