The real secret to the success of this conversion is the correct location for the coupler. It can be mounted on the inside of the firewall out of sight, or on the outside. Either way, it should be mounted in a position that allows the best lower shaft access to the steering box using the least amount of U-joints. Keep in mind that the goal isn't necessarily to get the steering column as horizontal as possible; it's to get it off the floor away from your feet. That could be achieved with the coupler mounted low on the firewall. The surface of the firewall could be a limiting factor. If it doesn't provide a good mounting surface, your may have to fabricate one or more mounting brackets. For appearance reasons, it's a good idea to keep the coupler as vertical as possible, but that's not critical to its operation. In fact, in this case the lower part of the case was pivoted slightly toward the framerail to let the shaft clear the headers. If the coupler in this photo looks funny, it's because it is a dummy case that Dave used as a template to measure and mock up the mounting position and the path of the steering shaft segments from the coupler to the steering system (in this case a rack-and-pinion box) in order to figure out the best mounting position. Wizard Fabrication will provide a template to customers with center holes marked for that same purpose.
