Compatible dark slides for Bronica GS-1 backs?

Just a simple question I was hoping someone might know..

I have a 6x7 120 back for my Bronica GS-1. I left the dark slide (with my incident meter!) where I was shooting the other week, never to be seen again.

Do any of the dark slides for the other backs, like the 120 6x6 or 6x4.5, or even the 220 backs fit the 120 6x7?

I ask cause I'm having a heck of a time finding the dark slide alone, so I'm starting to look for a cheapo back just for the part.

Thanks!

I know that the darkslides for the 120 and 220 6x7 backs are interchangeable and would guess that they would work for the 6x6 and 6x4.5 as well. You'll know they work when you slide it in and you can detach the back from the body.

Contact Jimmy Koh at www.kohscamera.com. He fixed me up when I did the same thing last year.
