Lost drive in all gears

OK now this one probably seems fairly straight forward but given the nature of the problem I know it will be very time consuming and costly of a repair.
I drive my 83 944 as it was meant to be driven (a true balanced sports car) and I do tend to give it a bit more gas that the average sedan and I guess this leads to the problem.
Last night while driving home from work I pulled out of the parking lot and went from first to second and got back on the gas only to loose all forward power (still had enough grab to get me a couple blocks if I gave little or no gas) but if I gave it any power it would slip bad with a terrible racket.
I parked it and got it towed home knowing this was bad.
Today I got under it to check the inspection holes at the clutch housing with someone running the engine and placing it in gear and the noise was in the front at the clutch to power tube. I checked the coupler at the tranny via inspection hole and confirmed that the tube was not spinning at all so the problem is at the clutch area.
I did not find any rubber shavings or bits in the inspection hole but I do know the clutch is engaging. The sound it is making is as if the splines stripped off and it is not on the splines of the input shaft.
Has anyone run into a problem as such so I know what I am up against when I finally get it apart?

My money is on the clutch disc itself. Either the rubber has fractured cleanly and hence no chunks, or the disc material has delaminated. Either way your in for a new clutch. Long job, but satisfying to complete. Much cheaper if you do it yourself too. Good Luck!

Wouldnt' think splines. Rubber center on clutch Ka-put would be my guess. Make sure you do the other overhaul stuff.. Rear Seal..
Hope it goes well for you.

After seeing a picture of a factory clutch disc with the rubber I am leaning towards thinking it seperated clean somehow from torque and was grippy enough to give me little movement but obviously not enough for torque. So now the question is when can I find time to rip it apart to repair it.
I have heard suggestions on complete clutch kits on Ebay from reputable sellers who get sachs parts. Is it worth the money to go with Ebay or are there great deals on online shopping like this site for example?
On average how long should it take to re&re a clutch kit with input shaft bearing ?

Time: 8 to 10 hours (depending on how much swearing you have to do).

Cost: Used kits available for about $150. New kits available from abour $400

While you're in there: Replace the needle bearings for the clutch release fork and the pilot bearing.

Used clutch... Correct me if I'm wrong... Isn't that like buying used brakes? Or better yet, used gas?

There are different levels of used. We happen to have a couple that were installed shortly before the vehicle was wrecked.

You would be surprised at how many used clutches we do sell.

If it's that old I'd replace everything that way you won't have to do it again. I just did mine from oil seal to throwout bearing and I know I'll never have to do it again. If the fluid is BLACK replace EVERYTHING.

I replaced the clutch master and slave cylinders 5k ago but I am getting seepage from the slave cylinder at the housing. I will get the whole shebangabang and be done with it. I would like to go with a better clutch if there is one available with a complete kit if not then the factory one is fine.

The one I installed was a sachs. So far it works great. I haven't even put fifty miles on it. Thats because I've been driving the 911.I'll drive the hell out of it this weekend as it is going to be very nice.
