Try AOL precision engineering in Gorteen Sligo, they might be able to make it, I remember being with a guy one day and he picked up a drive gear in it for the slew ring on a 4 ton Hitachi, they made it from scratch.
I don't know anything about them apart from that, there is a few members here closer to them than me, they might know more
