I forgot to get pictures of my mounts when I went back to the shop, but the pics are now up in the links. The Kitfox 5 remodeled mount I have does stick the engine a good bit forward compared to the Kitfox 4 mount. 4" I think. As I remember, the face of the prop flange is 29 1/2" from the firewall with the 5 mount, and 25 1/2" with the Kitfox 4 mount. JImChuk
