I have couple of new aftermarket dampers on the shelf, I'll have to check those to see if they are flat.
Just noticed on the FAST site that the new wheels are .125", not 1/16".
Just went out and checked the shelf. I do have several SFI and non SFI flat faced dampers. The other issue I had with the standard flying magnet wheel is the thickness. I have a March single belt serpentine system and there's not much meat on the back of the crank pulley that could be machined off. 1/16" is much more feasable than 1/4". I may not even need to have it cut as I have it shimmed out about 1/8" right now for belt alignment. That may change with the new damper. I've got CAD files of the crank pulley bolt pattern so I could have a wheel cut if I could find a measurement of the tooth height and width.

The crank trigger can be magnetic or hall effect it just depends on how you wire it into the ECU.
The cam sync can also be either magnetic or hall effect same thing.
You are right the Fast wheel is 1/8" and a hall sensor. The MSD crank trigger is 3/8" and magnetic.
