Help Finding Fuel Petcock

[BlueR32]

Looking to fit a simple aftermarket (aka cheap) on/off fuel petcock to the tank of the RD/SRX Project. I'm using the SRX tank but the existing outlet/petcock is beyond rescue. The snag is that the petcock bolt spacing on the tank is 45mm. Can anyone point me to something that could work?

is that the same as an rd400 spacing?

if so, yamaha raptor

RD400 is 34mm. I know Suzuki GT750 is 45mm but I don't want the vacuum activation.

You could fabricate an adapter plate to fit a different petcock.

Thanks guys! Also just discovered that Yamaha XS650 78-83 has a 46mm bolt spacing:

You can disable the vacuum portion of the petcock but then it won't have an off position.
