I got the FG-84R3D mounted last night, it went more quickly than expected. I do not have the Saito mounting standoffs so used shorter pieces I had on hand, and 1/8-inch plywood discs to make up the difference. Some of the firewall triangle bracing has to be relieved to accommodate the discs. Blind nuts were installed, the firewall relieved for the carburetor and it's ready to go.
