You are right about all that, Denny.
But, if you have to have the real thing, "they are not making them anymore", having an shiny/clean new original will cost you. "Serious" owners/collectors (with deep pockets and no patience) do not not care about the $$$.
Here is a discount valve - free shipping. But, you do not get the box.
If I was willing to go $100, I'd go the extra $20 and forget about this one? Or, put a Watch on this one and
see what the market will bear. Here is a deal:
the "normal" price is $350 if you can prove it is going on a 53-55 235 Corvette?
Non-original-looking "reproductions" are available, but some of us jerks know the difference.
I have experienced shipping charges that bad/high from Jim Carter when he has sent partial shipments of relatively small-sized parts. It hurts when you know the cost of USPS 2-day Priority Mail, with free packaging and free pick-up at the sender's address.
