On the hatch, I started out by knocking the blind-nuts out of the hold-downs. I drilled, tapped, and hardened the holes to accept 1/4" nylon bolts. I used #2 button head screws and red electrical tape for the canopy mount. Everything lined up and fit perfectly.

I had to enlongate the holes in the fuse where the landing-gear passes through. After that, it was a 5 minute bolt-up for the gear.
