Want to Buy Mamiya/Polaroid roll film back for Polaroid 600SE

Hi, I'm looking for a Mamiya/Polaroid roll film back that will work on Polaroid 600SE.
I heard the normal Mamiya Press/Universal backs won't fit unless there is a special adapter plate.
Since I'm running out of Fuji pack film, I need to use 120 film on the otherewise nice 600SE.
I'm based in San Francisco Bay area. Thanks!

You'll need a Mamiya "M" adapter to mount a roll film back. It would have to be one with the correct feet for the 600se. These are not easy to find, but you can adapt a Universal M adapter by swapping feet from a 600se-compatible pack film back. That's what I did.

Alternatively, there's a vendor on Ebay that sells 3d printed "M" adapters for the 600se. They're a lot flimsier than the real thing, but cheaper and easier to buy.
