I was getting tired and it was time to quit, so I just made some preliminary checks for the motor mount since the firewall s the next station. The top center bushing goes right through the apex at the top of the firewall station, so I have to fit the tubing around the bushing. Since I didn't take apart the jig I used for the firewall station, I can easily separate the the two halves, fit the bushing and retack it together to fit the Avipro mount exactly.
I checked the mount against what I had already tacked together and it was about perfect. At the top left and right bushings, there was a little gap on the sides. I used a piece of 1/16th welding rod as a go/no-go gage and with it spaced evenly I wasn't able to pass the rod through the gap on either side, so I'm good to go. Now off to bed!!!
