jstanton, is the engine box totally flat where the engine mounts? Will the 25GT mount on the engine box without the addition of another mount or will you need to use some sort of stand-off mount? Post some pics of this when ever you get to that points. What dimension does the manual give from the engine box to the back plate? Will the 25GT work in that space and be able to mount the cowl normally or do you think you may have to modifly it some?
