The case was sold to me as a modded DW case. But I don't see how it is possible to increase the diameter of the rehaut to fit a gen plexi.
The new plexi is (supposedly) gen, and it did fit the rehaut of the case exactly, so they must have had the same ID as the stock plexi. Of course, the OD was different, so I had to shave the bezel down.
The previous modder had put a smidgen of glue to secure the stock crystal in place. It is possible this took care of the amount of play between the new xtal and the rehaut. See also Lhooq's post here:

I read somewhere that early DW cases had different dimensions than the later ones, but I cannot find that thread now.
The other thing I did was freeze the bezel before installing it, that helped expand it a tiny bit
