Source for crank position sensor pin on flywheel?
 

I accidentally broke off the pin on the side of the flywheel which (I assume) triggers the 3.2's reference senders.
Anyone know where I can get a replacement pin?
I see a threaded pin in PET (93010222100) but it's $74 from Pelican. Surely that can't be it... I hope.

Flywheel Threaded pin.
 

Yes that is the one. Remember to put it in place with thread-lock. I believe my first install was sent into orbit, since I did not find it when I disconnected the transmission. Buy the 74 $ unit and save yourself a lot of trouble of finding a bolt with the correct stand off and thread pattern. If you had to drill out the broken section than a bolt with a larger thread pattern is the way to go. If you have the broken section you can measure the stand off. if not I believe it is 6MM..

If you do decide to get a bolt from the hardware store, make sure that it can attract a magnet. (Ferrous metal)

Ooops! I did not notice your 5400 posts general, please excuse the private...

Thanks, aquazulu.
Unfortunately I think the sheared off head is long gone. I am going to attempt to replace it with the help of this thread:

$74.................... absolutely ridiculous pricing.

Should be able to get a black oxide carbon steel metric set screw at your local hardware store. If not, Belmetric can set you up

Yes, that's why I was skeptical at first.
Shouldn't be too hard to find a suitable replacement.
I think I have some of the correct size screws at home, but they are stainless unfortunately.
