Brief Description: Drill engine mount to firewall using bushings.
Once the firewall is aligned and clamped and all the bushings made it’s an easy task to actually drill it. I drilled just the bottom holes down to 3/16” using the drill bushing set. I then replaced the drill bushing set with the shorter mount bushing set and bolted a 3/16” bolt through it. I only drilled the 4 bottom holes. I’ll drill the top 2 holes with the firewall back on the fuselage.
