1. Did some more filing and sanding on the fuel selector panel, then fitted it and secured it with black stainless #8 screws.
2. Fitted the fuel selector plate and handle. (I initially used socket-head cap screws for the plate, but they were too tall and they interfered with the free travel of the selector handle, so I changed them out for stainless pan-head screws that are about 1/16" shorter.
This completes the installation on the fuel selector panel, except for some minor paint touchups that will be needed later.
3. Changed out a steel clamp on one of the exhaust hangers. This will allow the cabin heat able to pass through this area better.
