I'm fairly certain that I saw a posting last week from Uly (Guinessdude) saying that he took the last three sets that Atlantic Speed had in stock.
Summit is your best bet, especially if you want them by the end of the week.
I'm sure other places stock them, but they probably will want the usual "Corvette Tax".
Make sure to specify they "New Style" not the "Yellow Ones". Make a big deal about it when you order, that way the request goes all the way back to the warehouse to the person who actually pulls them off of the shelf and puts them in the box.

Don't know anything about the Delphi, I didn't research them when I replaced my originals last year.

Good luck!!
