Depends on the RAM mount stud size, I've seen 1/4-20, M8x1.25, M10x1.25

 

I'm assuming these were all tapped the same. I want try to buy an aluminum ram ball as my rubber one is squished and my GPS is always slipping down. I can remove mine and see what thread it is, but I have it loctited in, I'd rather not if somebody knows what thread these came with.

 

Ordered mine from eBay right before my tour last year… here’s the link: (I assume you mean for the two side by side accessory holes on the MCL Sport Touring triple)EDIT: I see you meant the stem ball.....could still try this and see if you like it...mines great.

The MCL (and Helibars) are tapped 3/8"-16. You can't get this nut any more, so drill and tap the OEM and perhaps consider a nut on the hidden side.

Let usknow how much crud accumulates in that trough. I'd be tempted to drill out the cover plate to fit the ball mount.
