Show me a separated distributor cam and shaft. Are not the lobes all of the same dimensions?
Take a look at the "exploded view" of the distributor in ORD 9 SNL G-758. I see no reason why the lobes would be different dimensions.

I was wrong. In the AL-IAU4004UT and ALIAU4006AUT mil-spec submersible dizzys for the G740 M38 and G758 M38A1, the cam assy IS removable from the shaft and can be reinstalled 180 off. While the cam is in fact symmetrical, there is the "notch" for rotor positioning that becomes a problem when installed backward. I think I will stick with what I know. Gasoline.

There are times when having the TM for your MV is a plus.
