Jerking (ruckeln?) W114 250 CE caused by distributor radial play?

Ps: I have also found a spare distributor, an older type, the PFUX6(R) 0 231 301 008. I will dismantle it and see what maintenance I can do on it.

1) Where can i find a detailed manual or sparepart list of ALL parts (or servcice parts)  of the PFUX6(R) 0 231 301 008 or the PFUX6(R) 0 231 301 015 

Thanks in advance
