Crankcase plugs - Motosens sender adapters

Motosens' site shows their Valkyrie coolant temp sensor adapter as being M20x1.0 - and unfortunately, they're "closed for reorganizing" at the moment so no online ordering is possible until mid-September.

Does anyone know where I might get a couple of Valkyrie-compatible adapters which will take a 1/8-27NPT coolant temp sender? Secondly, are the oil and coolant galley plugs both the same size (M20x1.0)?

I'm going to 'roll my own' setup with Auto Meter and Cyberdyne (Intellitronix) gauges on mine and Blondie's two remaining Valks - and I really don't want to drill and tap the thermostat housings like I did on the previous two Valks of ours I instrumented. (That approach worked fine but if I don't need to tear the front of the bike apart to install a sensor I would rather not.)

Any help is much appreciated...
