Check this out. As long as the mounting hole spacing is the same, you should be ok.

Jake, I think most petcocks can work. The big issue is whether the adaptor plate will fit the screw holes and if the petcock tube will fit into the tank.

I have had to modify (slightly) both of my tanks when using the aftermarket petcocks.

You can look at my old petcock (actually you can have it) if you want to bring it to DK or to Bob's to compare. My old one might be similar to yours; not for sure though.

Blessings Bro!

Why are you messing around with a universal petcock? Order up a proper one from Z1 Enterprises or get an OE source. You can always plug the vacuum line with a screw and then run the bike on prime. Get a shut off valve to stop the gas flow when parked or use a clamp of some sort to pinch the line.
