That’s the second 2016 distributor I’ve seen with that date code. I’m assuming it was at one time an NOS replacement stamped February 8, 1976.
It’s hard to say. I’ve never seen one for sale with that date code. I would think that most guys that are chasing the correct Stage 1 part number are also going to want the correct date code as well.
I must have bought it back 15 -20 years ago when I when I was doing some 70 stage 1 restorations. I am going to move it to the parts for sale section. Location = N. C. Price = $600.00 plus the actual cost of shipping packing and insurance.
