Gear ratios - tech question (serious Quattro content)

["Robert B." <robbrauns@bb.eulink.net>]

Hallo Quattrofreunde,

I drive an 85 Coupe Quattro with 5 speed. Looking at a parts car: 89 Audi 90 20V. Are the 5 speed tranmission
ratios the same? If the ratios are different, which tranny should I use?

Oh, what's the Audi P/N for the S2 6 speed? I'll try calling the dealer to see what a new 6 speed would cost.
Just for fun.

TIA
