[s-cars] How to see a difference between 7A camshafts and other camshafts?

[Mike Fitton]

Those part numbers are incomplete, but...  7A cams should all carry a 
054 p/n, while AAN cams should all carry a 034 p/n.  Don't want to jump 
to conclusions, but it sounds to me like he's scamming you.  I'm just an 
ETKA nerd so I can't give you anything more visually indicative.

ETKA's part numbers:

1990 CQ
054 109 022 (exhaust)
054 109 021 (intake)

1995 S6
034 109 022 D (exhaust)
034 109 021 AN (intake)

-Cheers!
