widthIf you want to use the other rings you could. If you were going to do that though get them without the caber rings and save some money. Also be aware that the pop-up piston will increase compression so if you were wanting to remove base gaskets it may make the compression higher than desired.
I am a fan of Caber rings personally for a number of reasons. They are just a higher grade of material. They are incredibly tough while also being flexible - aka proper heat treating. The edges have a slight chamfer to them so they don't snag ports as easily and they just last forever. They are probably one of the best names in the 2 stroke world when it comes to rings for a reason.
What dimension are you measuring?
I have an MS380 wrist pin needle bearing right here in my hand and it measures 16mm OD x 12mm ID x 13mm W
Here just to show some visual proof this is 3 pictures showing an 038 wrist pin bearing and pin in the end of the Phantom rod and with the 038 piston I have as well (click the picture for a larger view)
