Mark, I'm in the process of a power steering conversion on my 68 KM-2500, is quite a different setup manual vs power steering. You'll have to look into a conversion kit for the frame like the ones for 66 and earlier trucks. In my case I found a 68 Chevrolet pickup that had power steering in the local Picknpull yard and cut that piece of frame rail then grafted it in my truck(remember 68 GMC trucks with 2wd still used a manual steering box with power assist ram. As far as the steering box and drag link I'm using one from a 70 K5 Blazer, I'll see how all this works out next month. The other thing to mention is the telescopic steering shaft is too long on the manual steering, I separated it and replaced it with one from a 71-72 GMC.
