I have a 1967 M20F. It has modern avionics (G5, GNS750, GFC500). We are having to make custom yokes. A great upgrade would be replacement yokes with configurable controls (thinking of my helicopter time).
Mooney does have upgraded (Leather wrapped) Control Wheels P/N 930031 series (old p/n 917024 series type EO 1st Prod-2) – ask your authorized Mooney Service Center to get price and availability.
