I know it'a a long shot, but thought I would throw this here just in case.
I used to have a 97 Audi A6 Quattro Avant and thought the one thing that would make the car better would be to have a 5-Speed Manual in place of the Automatic.
Well, Audi never made a 97 A6 with a Manual, so I started collecting the parts to do it myself.
I have the following parts that came from a 1994 100csq with 104k miles;
01A transmission, rear differential, pedal assy, shifter, rear diff actuator and switch, wiring harness for actuator and switch, plus a brand new clutch kit. I also have a front-to-rear driveshaft and half shafts from a 93 Audi S4. The only piece not included to complete the swap is a flywheel.
