Always be cautious about ANY dealership offering old, original NOS parts for sale. By now most of the NOS stuff as we know it is long gone! Unless it is a real old Dealership with basically the same parts people that have been there for 40 years may have a better chance of what they are talking about, and what we need. NOS to them is something discontinued maybe 3 years ago!
Besides you should only be going into the Napa Valley for wine!
