My non-Q has a mini spare tire; in the process of getting a flat tire replaced,
I noticed that this spare is low on pressure and of dubious age. Rather than
buy another tire that'll never get used, I'd like to get a standard spare.
Am I correct in guessing that in this type of wheel (84 5kS - 4-lug, alloy,
flat-faced 
with ring-of-sausage-links holes, apparently 6.5" wide), there are no size/bolt-
pattern/ET variations, such that I can pick one from a junk yard without
measuring
etc.?  (Or, now that I think of it, is there a part no. on it?)

BTW: it seems established that the Audi Fox is mechanically related to the VW
Dasher :) - neither of which I know the original names of, though the Dasher
seems awfully similar to the Passat of that period, but smaller (?).
Am I correct in remembering that the mid-70s Audi 80 is an Audi 50 with a trunk,
and since Audi 50=VW Polo, Audi 80=VW Derby (which doesn't sound right)?
