I pulled the flywheel off the crank without first making reference markings for the re-installation. Realizing that this is a balanced rotating assembly, that was a brain fart on my part. Please, I would like to know:

--> ?ARE there ANY reference features or MARKINGS on the flywheel & crank that I can use to properly mate the two together in their original orientation to each other? ?

Below are my notes on Features that may have relevance:
* CRANK: The only feature on the rear face of the crank is a countersunk hole that is on the same bolt diameter as the six threaded holes and cylindrically 30 degrees from the nearest mounting hole.
* FLYWHEEL: The most obvious reference marking is a punch mark, about 1/8" diameter, on the rear face of the flywheel and almost tangential to one of it's six clearance/mounting holes. ("Rear" means the side facing, or closest to, the back end of the car).

THE CAR: A completely stock (no mods) 1987 Mustang 5.0 with the original flywheel, clutch and pressure plate, etc. (i.e. it's the original unit that came with the car when I drove off the showroom floor in 1987).
Thanks in advance.
 
It only bolts on one way. One of the bolt holes is slightly offset, so the flywheel will only bolt on one way.

Toss the flywheel on and start all 6 bolts by hand. If they don't line up, spin it around until you find the way where all six line up

I'm sorry, but I'm getting a little chuckle out of this....... you took the time to look at the flywheel and crank flange long enough to make all the "notes", but failed to notice that the holes on the flywheel are not evenly spaced making it "idiot proof" to install.
