Idler arm

Wondering if you got this figured out yet. I have a 1968 barracuda with a QA1 K frame. I have 70 2 inch drop spindles and a borgeson power steering box. When I was trying to use the pitman arm and idle arm for the 68 the cross linkage sloped up towards the sector. Now trying to figure out what year parts to use for getting the center link straight and working. I am new at this part of the car. I didn't realize it was going to change so much going from manual to power on the linkage set up. Any help would be wonderful . I have tried a 70 idle arm and that pushed the linkage so high up it would have never worked.
