I put my mask on top of the top glass. I the opening a little bigger than the negative image size. Though I did get a glass carrier once that was used with the mask sandwiched between the glass, but I don't like putting anything but negatives between my glass.

I have a SETOPLA lensboard in my Durst 8x10's Tripla lensholder; I think these lensboards are pretty universal among the Durst enlargers.

I'm not sure about 'new' and 'old' Durst lensboards, other than I have seen some that are black anodized, whereas the older ones have a polished rim. I don't think the sizes are different.
