I have two things to say. IMHO, NOS is not always the holy grail that some people think it is. Some NOS is original parts that were never on a car and sat on a shelf somewhere. They are very likely going to fit and work great. However, some NOS parts sat on the shelf because they were sold and returned because they were either faulty or did not fit. In that case, did they get destroyed? NO! They either sat on a dealer's shelf for YEARS, or were returned to a parts warehouse where they were returned to a shelf where they sat. Some NOS parts are also a result of parts that did not fit properly on the assembly line. They were sent to a parts warehouse and sold as Mopar parts. They figured that if a body shop ordered a fender that needed a bit of tweaking, no problem. Don't get me wrong, I am NOT saying that NOS parts are not good, I am just saying that you do have to be careful. Specially with electronic parts. Electronic parts that have been sitting on a shelf for 50+ years may not work. Case in point. About 20 years ago, I bought an NOS gas gauge for my 69 Barracuda. It was in an original box, and it looked really good, but it did not work. I sent it into an instrument specialist. It cost another $100 to repair on top of the premium NOS price I payed. He was the one who told me all about NOS parts. He said he had to repair NOS instruments all the time. So I am saying that your NOS tach is worth what you can get for it. My guess would be

My guess would be $350-$400 if you can guarantee it works to the buyer.
