K frame confusion

If you swapped the k-frame to 73 up which does take the different motor mounts, , but you used the 1970 manual steering box an center link and pitman arm , (which for manual pitman arm is different than power) and used idler arm off your 70 , Then you need to get the 73 up proper steering box with the large sector shaft , and center link and pitman arm and idler arm to swap to power steering ,

On 72 back the pitman arm and idler install through center upwards towards the engine . On 73 up the pitman arm and idler arms go down thru center link towards the ground

If you get a steering power steering box off a 72 with proper power steering pitman arm small sector shaft could work as well .
