When was your car built? Later 1968 big block k-frames were power steering ready. You need a 90 degree adapter and the correct hose which is not available, you will basically need to have one made. The correct crank pulley has a smaller pulley on the inside and larger on the outside that almost hits the water pump pulley. I can post pictures later of what they look like.
It was built 8/18 in 67, I do have the adapter, and the crank pulley you described is one I have, it’s just chrome. I have headers also so will have to test fit, guess I just need high pressure hose and a belt. Great pic, Thanks for the help. Dave
