I ended up using a Sig 2 piece mount, and it installed just fine.Per the directions I useda piece of 1/8" music wire to keep the sides lined up. Theholes for alignment (music wire) are notthe thrust line. They are the center of eachside of the mount, and can be used as a support fora nose wheelwire if needed.A Dubro 4-stroke throttle linkage enabled me to maintain the 4-5/8" dimension from the firewall to the prop hub. I had to grind a little of the web for throttle clearance. I was on vacation last week (work at home) so no otherforward progress was made.

Sig has Koverall fabric and thinner, but no nitrate dope. Practa nitrate dope is the same as Sig. I ordered enough fabric for at least two projects (2 fifteen ft. pieces 60" wide).

I did get a chance to tour the Horizon Hobby warehouse last week. It is located on the west side of Champaign, IL. Very clean and the people that work there are very nice. Over 120,000 sq. ft. of Planes, Trains, and Automobiles.
