Brake Pump Rebuilt,
There are two versions one for the early models prior to 1972 approximately (VIN 12448) had a 5/16" union on the top of the brake pump or from 1972 - 1980 had a 3/4" union.
We no longer provide a core therefore this is not on an exchange basis, you ship your pumps to be rebuilt.
