GBA LCD Potentiometer?

Hi all,

I've been performing the AGS-101 mod on a few GBA's recently and I found one of the donor AGB-001's has a problem without an easy solution. For the one in question, it looks like someone removed the rear sticker and attempted to adjust the LCD potentiometer but used too much force. It now spins endlessly and the adjustments are very finicky.

Ideally, I'd replace the potentiometer without having to rob one from another GBA. Does anyone know the ratings for this particular one?

Thank you!

My schematic skills are not what they could be. Is this the potentiometer in question?
