Remake F15-02 lower LHS motor mount attach bracket. This slipped during drilling of the 3/16 holes. I think the 3/16 clecoes don't fill the hole as well as the smaller ones, and the part can move around. I didn't like the way the 1/8" radius on the outside of the part fit with the lower side panel angle anyway. This may have contributed to the problem. Remade the part paying attention to the fit of that outer radius. Now it fits nice and clean. Will drill later.
New bracket in place. Will have to start with final size drills.
