Drat.
Boost Engineering has essentially backordered the trigger wheel, citing a manufacturing problem that should be corrected shortly, hopefully by mid April. Since I don’t want to further delay running the engine, I will get it running with the 009 distributor and convert to EDIS later, though hopefully not much later!
In looking for something unrelated, I found a cache of missing parts, namely the bag-o-relays and relay sockets.
Once I get the fuel tank in order, I should be mere hours from trying to start the engine.
