[T3] Rear suspension bushings and another little question

["emilio tiraboschi" <tipotre@hotmail.com>]

<x-flowed>Hi all!
mechanic told me that the negative camber (a little more at the left side) 
of my 1970 automatic notchback could be caused by:

1. worn rubber bushings at the spring plate/torsion bar connection or
2. wheel bearing or
3. worn rubber bushings inside(?) diagonal arm

Is it right? And, if so, can I replace bushings using Beetle or SuperBeetle 
ones?
The other question is related to a minor oil leak. I think it comes from the 
vertical metal breather pipe that, in my car setup, is not connected to the 
oil filler tube, but has something like a rubber cap with a small hole at 
the end. The right heat exchanger cover (asbestos?!?!) is oily, there are no 
leaks coming from pushrod tubes, valve cover gaskets, crankase pulley. Any 
suggestionsabout fixing it?

Thank you in advance for replies!!

Ciao
