Actually you bring up a very good point, I like the tie rods to on top but when I was designing and thinking, look to me like the input shaft to the rack would be just about into the 1 1/2 " tubing cross member. I actually used the Flaming River rack with the 4" input shaft but had to exchange it for the short input so the swivle would be a lower to pass under the cross brace. It was quite a challenge as you know to keep everything in line as not to be too far off on bump steer and wheel camber when turning.
Screw in ball joints, yes, the same ones Pole Pos uses and yea, NAPA.
Good idea on the exploder rear. If I wasn't looking for a IRS quick change, I would take your advice and check that out.
