Manual to power steer question

I have a 70 dart manual steering column with the coupler. You do need the manual coupler because the geared hole size is different between the manual and the power steering. This was from a column shifted manual steering car, it is a pullout and not cleaned at all. The column shift units are not as pricey as floor shift columns. It has the key mechanism in it and would bolt in and work. I could bring that to you for $80.

I have a dirty manual FLOOR SHIFT column (the pricey ones) with the manual coupler. It also has the key and would work in your 75. Since it's not cleaned up I could deliver it for $125.

PM me and I'll get some pics.
