1972 Dodge Dart Swinger - tie rod issue - tubular subframe and many mods

I also have purchased this qa1 k member. I have installed it in my 68 dart with all the original 68 center link and tie rods as well as the 68 idler and manual steering box. My centre link also slopes down from the drivers side down to the passenger side.
With my original k member I spent time plotting the toe change and had to elongate the idler slot and shim the steering box to correct.
My car is a drag car so this was important. The car drove and handled very well so the efforts are worth it.
But now with the qa1 k member it looks like these corrections will have to be done again.
I called qa1 tech today and they did tell me the correct idler to use is a moog 7042 with is for a 68-72 a body, so it appears as though the
K member is supposed to use the earlier parts, but the geometry appears to be off. My idler needed a thick 1/8 washer under it to fit
Properly. This is all fixable but for what they are charging for this k member, I expected better.
