common rail leak off o ring seals for straight 6 cdi engine OM613 ??

Hi,

Anyone have an idea of a supplier for the leak off o rings on the Bosch injectors, I've found a supplier of viton rings of the correct dimensions, but the minimum order is for around 260. (incidentally it costs less than replacing the rail from Mercedes)
I replaced the whole leakoff rail a few years ago with brass ones off the internet but they don't do just the seals.

dimensions are : Cross section - 1.3mm x internal dia. 3.5, the diameter of the spigot which it fits on is 3.8mm so ID of 3.5 not absolute.

Someone suggested that the Bosch leak off o rings are all the same but am not convinced.

i remember finding some on Ebay when I had a W210 a few years ago. They were described as for Mercedes commercials but other than being green rather than black they were exactly the same thing and were being sold in small numbers.
