I am re-positioning several coolant elbows on my Rotax 912S. I am on a search for a M18 x 1.0mm tap & die set to clean up the delicate threads on these elbows and flanges. So far, the only ones I have seen are on EBay and are in China and won't come to my house for almost a month. Can anyone share a ready domestic source?

I'm going to try Lockwood tomorrow. So far I've struck out with Sears, local hardware stores, McMaster Carr & Leading Edge.

Anyone got an idea?

Thanks much, Skot
