looked up the part in the official parts catalog, but it just says, "clamping screw" and gives no size. Can anyone tell me the size of the screw (part #3 in the diagram)? I'm missing both of them:



Here's the link if you can't see it clearly here: dcauto.gotdns.com/images/full/944_2_USA_..._KATALOG/pg_0112.jpg .

special bolt from Porsche dealer. Try DARTAUTO.com but but i got 2 from the dealer.

It is a special bolt because of the long shoulder. specs: M10 socket cap screw 12.9 hardness 28mm shoulder 18mm of thread 1.5 thread pitch. See if there is a metric bolt seller near you. You may be able to take a longer blot that has the correct shoulder length and cut off the extra threads.

Make sure you use the right bolt. This is a rotating assembly and the wrong bolt might cause a vibration due to being out of balance. Remember when racing this shaft spins at 6000 rpm (at engine speed). Get the proper bolts.

I think I have this bolt at home, but can't check 'till tonight. I can bring it to the track. BTW, if you have the extra door bars for your cage (and they fit well), Ray Freundt can bring his welder to the track, and weld them in Friday night.
