Finished up-drilling all 4 holes to 3/8" to hold AN6 bolts securing the motor mount.
Trimmed the edge off of the right side upper mount as it was hanging off the edge from the prior trim.
Next, I cleco'd some of the interior parts back into place. The Homebuilt Help video noted that it was easier to put the seat bottoms in first, then the center console pieces. Since I'm about at the point to install the main landing gear spring, some of these parts need to be riveted in place first. Once the center tunnel was installed, there was no issue with getting the seats in, so that was a non-event.
