You need the clutch pedal assm from a manual explorer/ranger. Either just the pedal or the whole brake/clutch pedal assm. You need the slave cyl and line.
The m5ord is the same length as the A4LD so no driveshaft or crossmember modifications needed.
You can pull up the carpet and theres an access panel you can remove to put the shifter through the floor.
Then you need to either wire in a NSS or just jump two wires in the loom of the auto NSS to allow the starter to crank.
