I was removing and installing my wounded cowling million times. Back and forth hundreds of clecos. I also plan to install camloc fasteners and it was a pain in the neck to fit everything to firewall. What I did I riveted camloc attach strips with required shims to the flange using keeper rivets. Much easier to shuffle the cowling this way.
