TIP: Did the above by measuring and marking all the shapes and holes. A better, faster way would be to use a pattern from tracing paper and glue it to the angle.
TIP: To bend the angle the required 4 degrees, I used a large crescent wrench per the Jeremy Monnett Homebuilder Help video on the EAA website. It worked, but left small gouges in the fillet of nearly all the parts, which took a long time to remove. Best removal method was with a small Scotchbrite pad mounted on a drill.
