    Are you sure your E-Brake is not sticking? I would think if it was clutch chatter it would also happen in 1st. Try taking off in 2nd and see if it does it.

    Way back when I had my 64 coupe (40 years ago ), it started doing the same thing. I just lived with it and later it started doing it in the forward gears....it was an easy fix though. I added a small bottle of Positraction additive to the rear end. Maybe your issue?

    I had the same issue with my Polo Green 96 after I replaced the clutch. I would get chatter in reverse, especially when backing up an incline, or hill. Once I drove the car for a few hundred miles, the chatter went away. I think the clutch just has to be broken in, you should be fine.

    Good luck, oh and lets have a look at the car, when you get a chance.

    I'm with Toms01 on this one. Sounds to me to be a posi problem. Try changing diff fluid and adding the posi additive.
