Welcome to the Club, and all that.
Um... so if I understand you right, you've already got the old sensor off, and the new one on, sorta?
Seems like it'* just two bolts that hold it on, right?
I've never done it myself, but it looks really straightforward.

There should be two bolts that hold the bracket to the engine & another bolt (see image) that tightens the sensor in the bracket.
The sensor alignment tool is very expensive. $400 some dollars IIRC. I used a .020 feeler gauge between the sensor & harmonic balancer.

Your sensor ahould not be loose in the bracket. Only when you loosen the hold down bolt. Maybe yours is missing. Get a bolt and adjust it with a feeler gage and tighten it down.

Would you please put your year make and trim level in your sig.

The feeler gauge is used to measure the distance between the two parts and to set the sensor the proper distance from the teeth on the pulley.
If you can figure out how to put Yo in your signature line, you can figure out how to put the year and model of car you are working on. It is a handy quick reference for the site gearheads to distinguish between the different parts and maintenance procedures on different models. When you ask for help, it is the best way to help them help you.
