Geez. I know that mount is a bummer. But it is nice with no exposed screws in the cowl. I friend got that ARF last winter for a song. If I had a spare I would have sent it along I have two of the 1349 and 1359 arfs Don't use cowls on either as I have radials in both planes that don't fit. I gave the cowls away to folks who needed them. I think that internal ring was the same!
