The 360 crank sensor fits to the 360 bell housing, not the block, and I think B19 360 did not use a crank position sensor. It was either breaker points or hall effect trigger in the distributor.

You need to either modify the 360 bell housing to fit the block mounted bracket or get a B200 bell housing (I guess these are different, unless the B19 bell housing has it).

I'd prefer the 360 mounting rather than weakening the B19 bell housing. Other options are to make your own mounting by using a precise insert to get the height, or to make a custom pickup somewhere else on the engine.

You can use various clutch pressure plates, different ones give different holding pressure. You need a friction disk that matches the 360 drive shaft. The 360 disk is only 215mm but the rest of the parts are 228mm, so the Audi disk is 228mm and fits the 360, or any B2xx solid flywheel.

All solid flywheel 200/700/900/360 use similar clutch cover, but the 360 one is a bit flatter at the edge to fit the bell housing. You can just grind down the edge a little for one designed for the bigger bell housing.

I'm not sure the crank sensor matters very much but you can make any sensor fit.

I just ground down the corners at the edge of the clutch.

I have seen that flywheel and I think it needs a different computer system than the Bosch EZK, I'm not sure yet how critical the pickup is.

Mine is a 940 solid flywheel (almost the same as the 360) for Bosch EZK ignition.
