I'm converting my 6 from LHD to RHD and I'm not sure as to how the speedometer and tachometer cables pass through the firewall to get behind the dash. I've read all the previous posts on this subject but none tell me whether both the cables enter through the one hole/grommet or is it one hole/grommet each. All the pics I find on RHD cars seem to have only one hole suggesting both cables use the same entry point, but this seems a little tight.   Thanks as always Dex
