Do you know any kits that would fit it and have a 00 key
Most GBs lately have been featuring an extra blank or two to accommodate. It's certainly feasible to get a set that would handle it.
If you're looking to buy right now, I'd take a look at PMK to see if you can get yourself some blanks. I'm not really sure about who else would have numpad kits on offer.
If you're not looking for blanks, I'd take a look at currently running GBs and ICs.
