Auto Plug Adaptor Suppliers?
 

OK,

I'm talking about the reducers that allow auto plugs to be used in aircraft cylinders...

Claus makes them, Emag makes them... Anybody else? Any good deals out there? Anybody making them in their garage for something less than $65.00 a set?...

After looking at $3.00 brass reducers in the Home Depot aviation department, it appears that the price for the plug adapters is no where near in line with the technology required to produce a part like this (and yes, I have a good handle on production volume/price theory). :D

Thanks all

I have a new unused set. 50$ shipped.
