Gold plug part number question

[Brazos9]

Ive seen a couple posts that show MP-01 as the part number for the gold plug, but in the same thread ive seen mention of a "new shorter version". Is MP-01 the new shorter version, or is there a different part number? Thanks in advance.

This is the MP-01. I haven’t seen a different option from Gold Plug, but for reference, the threaded section and magnet extend 15mm beyond the washer. This readily fits below the screen in the 125cc motor.

Thanks for the measurements! Those have been more difficult to find than hoped.

I got mine off Amazon. I'm not saying they're the cheapest around but they are definitely in stock.
