Help! Need parts advice.

Hi quatrro listers!

In process of suspension repairement of my '85 Audi 80 Quattro I've
met with some difficulties of getting aftermarket parts for this model.
So I am again with question about compartibility. VAG parts number
for my rear springs is 857 511 115 C (white marked) and for rear
shoks is 853 513 031 B (yellow marked). I am suspicious whether they used
the same parts for other models - earlier or later FWD 4K, 80, 90, or
later 4KQ, 80Q, 90Q? Or maybe for some VWs?
Unfortunately I have no access to different fiches (only to my model) so
I kindly ask those of you who has fiches to confirm or to deny this idea.

With best regards

Maxim,
