More minor modifications to the AC Spruce air box. The camloc fasteners didn't match the hole spacing of the Brackett air filter specified, so the camlocs had to be drilled out and new holes drilled after a sandwich patch with .025 4130. Next, 8-32 nutplates were placed. The bottom air outlet has to be cut short to fit within the tunnel. In addition, I skip-welded fender washers to better support the air flap shaft, as Mark Goldberg reported the holes were wallowed out at his first annual. I also replaced the stock nylon bushings with Teflon bushings, which have less friction and hopefully will last longer. I also welded additional metal to the carb heat cable support arm, as it was flimsy, and placed some silicone sheeting for the air flap to press against.
