I have a bunch of Mercedes diesel injection stuff..

[tdi994me]

I recently aquired it from a friend of mine who rents out a automotive shop and he gave it all to me. Problem is I don't own a mercedes and want your opinion and expertise on what I should do. I got a bunch of different sets of injectors and even brand new nozzles from him. I don't know what year they go on though!
Sets of old injectors:
KCA30S46, KCA27S55, KCE27S3, KCA30S35/4

He also gave me a bunch of nozzle tips:
DNOSD261,DNOSD265, DNOSD310. If i remember some of the 261s are from Germany and some are from France. The 265s are France and the 310s are Germany.

What do you think I should do with them? I don't have the stuff to rebuild injectors and would rather take as little effort as possible while still benefiting. If you have any info on these parts, please feel free to let me know! And heck if you help me out i can give you parts maybe? I might be missing some of the part numbers. HELP!
