Piston stop pin

[00Dan]

Anyone have a model of a piston stop pin? Alternatively, would someone who has a pin be willing to dimension it so I could model it myself? I’m looking to print one so I can validate my flywheel’s timing marks.

If you take an old used spark plug and drill it out inserting a bolt long enough to reach the piston before TDC you have a piston stop pin.
Drill a hole from the side to lock the bolt in place with a screw.
The length of the bolt is not important as long as it stops the piston.
