PN for Mercedes injectors?

["Sherry & Chuck Clark" <clark@rmi.net>]

Hey all,
   Thought I'd drop a quick line to the list to see if someone
knows the correct part number for the injectors with the
fine threads (same threads as the 5ktq).

Mercedes lists two part #'s for the 560 SEL.
 
 Bosch part #'s:
 0437 502 035- I'm assuming these are the fine threads
 0437 502 047- assuming these are the larger, thicker threads.
Any help to decipher these two #'s would be greatly appreciated! 
Thanks,
