Ofrei's pushers are the same parts that Rolex fits nowadays (just cheaper). Whether they will fit a given DW case is impossible to say, because the cases tend to vary a bit. The gen/Ofrei pushers fit some DW cases, but not others. The only way to know is to try. Unfortunately, in my experience, when they do not fit it is because the holes in the case are slightly too large. In these cases, the only (realistic) option (you could weld in new metal & then tap a new screw hole, but I think that is more work than the case is worth) is to reinstall the DW pushers or cement the Ofreis in.
Rolex used 3 different styles of screw pushers on 62xx Daytonas, but I have only seen the last version (which is what Ofrei/Rolex currently have) available for sale anywhere. I posted a thread a few years ago that showed the different pusher styles, but it may have gotten lost during 1 of the previous board upgrades.
