I'm converting my 67 GS CA. Special from bench to buckets and I'm adding a 3 speed console & shifter from a 67 GS400, but I'm unsure of the rear shifter mount location and it's height. Anyone have any ideas? I need these distances: * The distance from the rear seat lower vertical step, at the hump, to the rear shifter mount location holes. * The height of the rear shifter bracket from the top of the hump. Thanks,
