Petcock Identification help!!

[tmtrebor]

Hey guys, I have this tank I plan on throwing on my bike, but cant confirm what petcock will work. can anyone identify it? I believe it's a kz650 tank, but I'm not finding anything but the stock petcocks. Looking for a smaller, universal one, but not sure where to get a mount.

If anyone has experience with this, that'd be great.

Looks like my buddies '83 KZ750 tank. Have you checked Z1enterprise for their 750 petcock?

Measure between the mounting holes and post a pic of the whole tank.
