I got the overlay for my 090 from archibald, he is the only one who made them (thanks once again, J.!)
Unsure if he is still making them, though.
You may try and make your own overlay as well, even if not at archibald's level as he used a special hi-res, 4-colors printer, as well as special stickers and cutting tools.
What you need is a good printer, thin but bright white paper, and a scan (or, even better, a vectorial file) of a gen datewheel.
If you are interested I can send you a scan of the datewheel -- a normal .bmp file, not a vectorial file, sorry -- and the exact size you should print it.
In consideration of how bad is your datewheel, even such a homemade overlay might make for an improvement in the end.
