Rocker shaft end nuts that hold shaft from backing out? What's part?

[JoeMag]

What model 911's were these used on? See item in circle in pic. I can not seem to find in pet any where. Missing in pic is a ring with a small shaft on it -- ring: goes under cam tower nut and shaft fits into hole in rocker shaft nut.

Mike -- Did a part search on parts you noted and could not find them. Here's better pics of what I'm looking for. Which part number goes with which?

HI just which bit of the thread did you not understand, was it the bit with threads or the bit without threads or the lock washer, has the one in the photo with threads or without, try the part No's at andial,supertec,john walkers workshop or a race engine shop for 911 engines, or you could ring the competition department at Porsche or or take the No's to you opc and get them to check for price and availability for you.

regards mike

PS. the bits you require are from a 935 engine, hence the part No's from the 935 parts manual

Mike -- Thx. Let me see if I have this straight.

- The washer (item on left in pic above) is 930 105 342 00
- The item on the right in the pic above has threads on the left end of it, so that is part 930 105 343 00?

thx, Joe
