Rear differential mount

[Radek]

OK, so I checked the diameter of the bushing on the car - 64.5 mm (+-).  FA 
shows these under early 80s Rabbit, 64.4 mm and 75 mm, three part numbers. 
I called the dealer and they verified that the 75 mm is obsolete and so is 
one of the 64.4 mm ones.  However, the third number worked (171-199-214H) 
and they were able to bring one in.  Unfortunately, the shaft for the bolt 
is not in the middle - it's offset quite a bit.  Not good.
I checked 034 and found a solid rubber bushing they sell for this purpose 
specifically.  Called them to verify the size - they tell me that because 
there were several variations of Audi castings, they make it 65.4 mm in 
diameter so it fits most.  I'm thinking, a milimetre too large, it won't 
fit.  They suggested sanding the opening to enlarge it.  Pressing an 
oversized steel piece into a smaller aluminium opening may break something. 
I don't think I can sand the opening by hand and keep it round - perhaps 
oval, but that's risking breakage again.
Any thoughts?

Thanks.

Radek.
