Back again with an 'out of the norm' tech question.
I'll modify the engine to run on a carb instead of the elactronic FI unit so it will not need the ECM... I still have the stock distributor to deal with.
If there isn't a "bolt-on" swap one that will work with out the ECM, then (with some modification) couldn't I take the drive-gear & lower mount section of the stock one & adapt it to the lower part of a different (4 cyl)distibutor... or just swap-out the guts to resolve the ECU dependency.
