Installed the vertical L extrusions to the front spar section to th 1/4" bolt holes. Marked and drilled rivet locations and pilot drilled into the L's and backdrilled through the packers. Aligned on the spar with the 1/4" bolts and backdrilled the rivet holes through the spar web. Enlarged rivet holes to A5
The two outer angles were prefitted to my aircraft for dual sticks.
