[s-cars] Bilstein Part Numbers

[calvinlc at earthlink.net]

I am looking at possibly buying some Bilstein shocks for my '92 S4 and I was
wondering what are the correct part numbers for the stock '92 springs setup?
There are 3 different part numbers I have seen for both front and rear and I
am a bit confused.  Thanks!  BTW, how long of a job is it to change the
shocks and struts on these cars?
