I've embarked on a panel-redo, and I've hit a snag and need some advice. My 67C had a shotgun panel that featured an EGT gauge and 4-cyl selector right in the middle of the panel. I plan to finish my IR this year, and want a six-pack instrument arrangement. The a/c has a Radair 4-cyl EGT with a single gauge and a selector switch. The panel mount rotary switch is 2-inches in diameter, about 2-1/4" dia. with wires attached. It is in the middle of the photo resting atop the TC. The single-channel EGT gauge itself is just below the AH. Re-designing the panel to have a six-pack arrangement, with CDI and Dynon 2 EFIS between the six-pack and radio stack, the 2-1/4" EGT gauge must go to the left side below the key/master sw. There is no place left for that huge selector switch because of its 2" diameter. The switch is made by Shallco. I also include a diagram of the new layout. Any suggestions? Does anyone have a smaller switch idea? I assume that the red/yellow wires on the EGT are the dissimilar thermocouple wires and I need to be careful about cold junction error when selecting a switch. I have been scouring the interwebs looking for smaller switches, but have not had any luck. It seems that this calls for a 2-pole, 2-deck, 4 position switch. Son #1 has access to a water-jet cutter and he is going to be cutting the new panel next week. :-)

hi everyone I own 67 M20F it recently went down for annual and the flange for the induction tube was damaged, so I contacted Lycoming and they sent me a new pipe which superseded the previous part. this new tube appears to long. Any tips for installation, modifications, etc thanks

Anyone know the part number for the metal can and shroud that go over the fuel pump and where you can buy one?
