Ron,
What we need is an outline of the the entire firewall area with thrust lines included, in other words he needs the outline of the front of the fuse where the cowl will fit over it to see if his cowls will fit. I guess he needs the thrust lines to tell if the front opening on his cowl (where crankshaft goes through) is in the right place.
The fact that you cut the stock mount off will make it a little easier to do.
Thank you for offering to do this for us. I'll have to send you pics if it all works out.
By the way, what engine are you using on your Pitts?

Thanks, Jim
