Are ebayers outta their minds with the prices????

Yea. Any car with limited interest is like that. Try doing a lesser popular B Body.
"They" aren't reproducing things. And that which is reproduced isn't in quantity enough to bring the price per unit down.
And then there is just the cost in general of things these days.
Even standard hardware.

Nothing you don't know already.
But sharing the pain is what we are here for.
That ebay seller is Tops by me. Oldsmokey. He has shipped hardware to me for free. Really. I know you are just using that as example.
