Secured cowling side hinge pin guides using smaller Adel clamps and some RTV sealer at the firewall. Only had a dg2 and 3 Adel clamps. The dg3 is the perfect size for the stainless tubing and I made the dg2 work, but need to order some dg3 clamps for the Bowden cables as well so I'll replace the 2 when I get those. Made a hole for one of two firewall pass throughs using a step drill and finishing with a hole punch. Used a location from an existing hole I covered. The previous owner mislocated the hole for the brake reservoir which was not supported by an aluminum angle, so after putting the reservoir in the proper location I had an extra hole in the firewall. There may be a problem with it interfering with removing or installation of the battery, but I'll deal with that when I get my battery. May have to trim the battery tray.
