final drive fill tool

Gone are the days where one would fill the transmission and final drive till the oil dribbled out of the fill hole. So much for progress; just look at cars that no longer have a dipstick. Heaven forbid if a driver got their hands dirty or got dirt under their finger nails. :rolleyes My R1200...

Question re. final drive oil change. Where can I find the aftermarket tool for injecting oil into the final drive unit? While I managed to use a regular syringe, but it was messy, left a bit of a mess.
