The 88-3 HOLLEY brand voltage regulator is a new  NOS vintage part made in the United States, and it interchanges with Standard Ignition  #  VR 35 specifically for 1956-64 Ford and Mercury vehicles and more. These regulators have been sitting on our shelves for about 30-35 years, some have a little bit of oxidation on the mounting base as shown in the pictures, but take a look at the inside pictures you can see that they are new and the inside looks great. I have cases of these on the shelf so if you are interested in volume let me know.
