DPM Conversion Kit -- which plate material

[jpfulton248]

I've been offered a used DPM conversion kit which apparently will allow my DPM 2340 to take plates on a bulk roll. I'm looking for 12" paper backed plates preferably 7 mil but will do 8 mil if that's all that's available. Anyone know the exact plate material I need to buy? I know sometimes plates can be rolled emulsion in which is what I don't want.

Thanks! Link to conversion kit below...
