Hi ray,
A little proding may help. Maybe intent to order a complete engine or parts to build up a corvair from them would get their attention. Nice people dan , rachel, and their 2 sons. I had the pleasure of sitting at their table at osh 18 at the thur nite homebuilders dinner at the nature center. I would assume they would need a set of plans to work from. you could build up the cowl from their plans and nosebowl.
Another avenue would be to contact bill clapp at
www.azaleaaviation.comMaybe they can build up a mount for the sonex B’s
good luck!
