I'm converting my S6 to an RS6 and am trying to figure out some differences:
Mainly (starting from left to right):
The frame rail area where the front motor mount bracket goes (pic of that area plus the aluminum mount, itself)
The area where the A/C lines and drier are.
The fuel supply, return and EVAP lines where they meet the hard lines.
The holders on the front firewall that hold the O2 sensors and other misc connectors.
The whole cowl area (coolant reservoir and wiring)
The dimensions as to where I should drill the holes in the front firewall for the small manifold that has the three coolant hoses.
The EGT sensor box mounting points
The ABS controller and its mounting pieces.
The frame rail area where the coolant solenoid is mounted.
Any help would be greatly appreciated.
