Junkyard EFI swap, 4.0 flywheel help

I'm doing a junkyard EFI swap into my 83 Eagle wagon, keeping the .030 overbored 4.2, also using a 4.0 head, and ax15 transmission. I wanted to save some money and figured it would be more worthwhile to just swap an ax 15 in and use the sltock location for the cps, the bellhousing. The problem is, I'm sure the 4.0 flywheel is notched accordingly, and I'm not sure if there's a certain way I need to install it, since I'm using a stock bellhousing mounted sensor, instead of paying 300 dollars for a crank damper. Do I need to have the crank lined up in a certain way before bolting on the flywheel so the sensor reads it correctly?

The flywheel can only go in one way.

OK-- so how do we ensure it goes on there correctly-- I'm thinking this is covered in the stroker section, as a stroker utilized the 4.0 flywheel on a 4.2 crank.

Let's search...

The bolt holes in the flywheel will only line up with the bolt holes in the crank one way.
