I installed the top cowling Skybolts.
Since I didn’t use the Skybolt flanges, I needed to drill out both the cowl and the custom built flange holes that I’ve been cleco’ing so far for holding the cowl in position. I used a step drill to take a section of holes out to 15/32″, removed the cowl, and drilled the flange holes further to provide enough clearance for the retainers. A tapered hand reamer is handy for touching up the 15/32″ cowl holes slightly to fit the rings.
I used floating retainers for the lowest position on each side. These allow a bit of up/down movement, not sure they were necessary but I put them in anyway as they were part of the kit.
