$100.00?!?!?!? thats insane for 4 brass plugs. I am soooooooooo in the wrong business..... i think they are the same thread pitch as spark plugs. just go to your local hardware store or parts store for some solid plug fittings. 12x1.25mm I THINK....id double check that though.
i just cut the threaded area off and weld them shut.

I found out , it's a 14m x 1.25.
