Not quite finished, but getting there. Before and after pics:
It will be going to Europe, hence the antique ADF, which will soon be joined by an almost equally antique DME. Waste of time, never to be used, but will keep the Euro-bureaucrats happy. Hopefully one day there'll be a proper autopilot too, but that will have to wait a little longer.
Actually the title should read "total restoration" rather than "panel upgrade". Newly sealed tanks, long-range fuel, alternator in place of generator, lightweight starter, new everything under the cowling except the engine itself, new suspension rings, new seats, new interior panels being fitted, soundproofing, carpets..... hopefully this 47 year old airplane is going to have a new lease of life as an unbeatably efficient machine for travelling around Europe, topping off the tanks only when I fly near one of the few low-tax countries!
