I've got most of the details of the shifter mount worked out. Assuming it's stable enough when it's done, if not I'll have to add to it. This is a test fitting, I made four spacers out of conduit that you can see on the floor. They put the knob or tee handle in just about the same location relative to the steering wheel as I have in my Camaro, which I find very comfortable.
I wound up using bolts from the bottom so there would be minimal protrusion toward the driveshaft. I have lock washers on both sides and a nut tightened down on each, giving the effect of a stud coming up.
