Online Community of Zenith Builders and Flyers
William Wynne manufactures motor mounts for the Corvair engine on a Zenith airframe. Sport Performance Aviation are the folks selling his products, you should contact them at "flywithspa.com". This engine mount will work with any Corvair engine. I find SPA great to deal with and they sell a full line of Corvair parts and accesories.
Happy New Year!
I am familiar with SPA, checking my options etc
