Sounds like you own either a 70 or 71 911. They used a 225mm pull type clutch with a 901 gearbox. I have a converted one in my 914.
They used a fairly weak clutch pivot. The only way to fix this is to pull the transmission. Once it's out, then you can replace the pivot with a hardened steel one, available from our sponsor. If the threads have pulled out of the trans case, dont' try a heli-coil or anything similar. You are only asking for the problem to come back. Open the trans up and remove all the components, including the differental (now is a good time to replace all the seals). Have a machinest make a top hat shaped insert with the proper threads (8mmx1.25 IIRC). Machine the case to accept the insert as a press fit from the INSIDE of the housing. If this is done correctly, and you put in the hardened steel pivot, you will not have the problem again. Hope that helps.
