Model A Water Pump Nuts
A very good quality water pump pack nut. This is a good heavy nut like the original. Available in Brass or Stainless. Brass nuts are import but very good quality. Stainless nuts are U.S. made. Stainless resembles the original zinc nut. Brass was originally used in 28-9 and zinc in 30-1 but either will work on any year, strictly a cosmetic difference.
