Konica Hexar RF ISO Dial

[Kumachrome]

Hello all, I'm in a bit of a predicament. The ISO dial on my Hexar RF is broken. The plastic plate on the top of it snapped as I was changing ISO. Well, now it's stuck on DX mode, which is fine, but a bit inconvenient. Any idea how I can source a replacement ISO dial? Perhaps someone here has a broken Hexar body and they'd be willing to sell me their ISO dial?

Thank you.
