1968 Dart radio bracket question

I posted a wanted ad for the bracket and mounting screw. I saw the links S'Cuder posted but unfortunately I guess someone else did too and someone bought the one on ebay that had the nut and screw. Some of the sellers on ebay sure are price gouging too. $10.00 in shipping for that tiny bracket? Greed. Anyway hopefully someone here will have one.
If anyone here has an original dash screw and can tell me what the original factory correct size was I can try and find one at the hardware store. Hopefully someone will have both pieces for sale.
