Permanent 4 drive train

I've just bought a 33, permanent 4. The car has all the normal alfa defects but i'm a little worried about the centre prop bearings and the viscous diff.:
Has anyone had any experience with this or know a good source for parts?

If nobody answers, try this forum:
I think there's a mounting that normally breaks or something.

Re: Permanent 4 drive train

the coupling tends to be ok.
but there are rubber bushes under the floor which wear and lead to banging noises and/or juddering on full lock especially. one of these (IIRC) is shared with the 75 and still available the other one however is not !
i have had 2 P4`s and fortunately both were fine,
good luck with your new car, theyre a lot of fun them things
