Bagged W126 build log update. Finally sorted the rear airbags. The Easystreet ES-2200 kit had been giving me grief since November - the rear bags would deflate overnight, dropping the chassis to the bump stops.
Turned out to be the rear air-line check valves (the Easystreet plastic ones) cracking from cold-cycle stress. Replaced with the brass Firestone equivalents ($28 each). Bags now hold static pressure for 14 days. Build complete.
Photos at the next cruise.
