the reluctor ring is only used on 96-97 lt1 engines so misfires could be detected on obd2 cars, it is under the timing cover on the crank after the timing chain and gears.

There has to be a key way. If not, then I presume the hub just goes back on the same way it came off.

The bump on the hib lines up with the key on the crank.
