Thanks guys, this is the sort of info I was after. The current leadscrews are 16mm and mount into what I would say is a normal ballrace.

Rich, Are you sure they are leadscrew and not ballscrews.? Asked before in other thread but if you can post better pictures of both the screw and nut it's easy to tell.
One clue if it's a ballscrew is to look on the top of each thread and you will see C shaped grove.

I've put a video on the other thread, maybe you can tell from that. I can't see any kind of C shape in the thread and the advert didn't say anything about ballscrews. Just said 1204 trapezoidal screws, and I've just measured them and they are 12mm not 16mm. It is the slide rails that are 16mm.
