I have always used the stock outer mount. On the inside both the square plate and round washer kits will work, it just comes down to which fits in the place you are drilling.

I moved the seat forward until my extended arms met the top of the wheel at the wrists (someone suggested that for a more comfortable arm position) and it looks like I can probably use the outer mount point from that far forward. Does the bracket need to be free to pivot? The OEM hardware is too large above the shoulder to fit into the opening and I can't find a shoulder bolt that's 7/16-20 thread with a 0.500 shoulder. An eye bolt and clip would allow it to move freely at the expense of a longer bending moment. Hmm...

I've read that the belt should ideally be mounted equally on both sides of the seat, so that puts the inboard mounting point right about where the e-brake cables come through the floor pan (the white rod in the picture from the center). There's probably just barely enough room on the "tunnel" for a backing plate but it would have to be welded to give me confidence in its structural integrity. Otherwise I can use the floor pan next to it, assuming there are no reinforcements or other obstructions directly below.
