1990 300e Distributor rotor broke loose!!!!

1990 300 E stalled while driving 40 mph. After investigating, I found out that the rotor collided with one of the posts inside the distributor and broke loose form inside the cam!!!! Now the post that holds the rotor came off it's seat. WHAT NOW?? Do I need a new cam or is there a remedy to affix this post back into the camshaft?? The small stud that hold this post inplace broke off from the cam.
I can probably hold it inplace by putting the car in TDC and applying locking nut to the post that holds the rotor inplace... IDEAS please..thanks for the help!!

Why did the rotor collide with the cap? I had an '89 300E that the bolt head that held the rotor carrier in the cam broke off and allowed the carrier (T-shaped bracket) with the rotor to migrate forward until contacting the cap. If the bolt head is broken, you can E-Z out the bolt shank and install a new bolt to hold the bracket to the cam. That might be the only problem.
Use a mirror to look into the recess in the center of the rotor carrier. There should be a torx-head bolt (might be hex) holding the carrier in place. If the bolt is intact and the rotor and carrier are still floppy, you may have a serious problem with the cam. That's beyond my experience and will require advice from others.

It's "NOTCH" that simple...

I pulled the "T" bracket out. Bolt and all but there is a Torx bolt still inside. The notch that holds the T bracket in position for timing puposes is the one that broke off. I can probably remove the Torx screw that also serves as a receiver for a smaller torx screw that holds the "T" bracket aka Rotor bracket. Without the notch, I need to know exactly where the rotor bracket needs to be positioned and probably use a locking washer to hold it in place. There should be no resistance once the rotor is in place because all the rotor does it rotate with the cam to distribute spark to the spark plugs at a given timing.. So the issue is the missing notch inside the cam hole. Such a simple thing to invest in a new cam though... I'm sure that there is a more econimical way to fix this issue other than the obvious solution..Thanks for the input
