How ya goin' mate

The STC is owned by a company here in Michigan and is for sale. He has all the drawings, some parts, jigs, etc. The whole lot was listed on Trade A Plane but it is not showing up now. I assume he let it expire. I think Larry probably knows who it is. I think the company is in Gaylord, MI. I will look into this a little further and try to post the info.

Not only can you convert your plane but you can buy the whole program.
