Trouble finding replacement gas valve for Carrier Weathermaker 8000!

I've been all over the internet through various sites and a few phone calls to no avail! Why should it be so hard to find a replacement for a simple 2-stage White Rogers gas valve to such a popular furnace? Even on the White Rogers website!

Simply looking for a replacement for a sticking valve. Can anyone share info on an equivalent? 1/2" ports.
