Adding power steering to a 67 frame.

[68SWB4x4]

Well it is a 68 4x4 but it has the same problem as the 67 where the frame is not "stamped" for p/s I know you have to drill a few new holes and heat the frame up and pound it in to clear the p/s gearbox or add some sort of spacer. I don't think a spacer is a good idea with the frame cracks in these trucks. But My question is what of the orignal three holes do you go off of? I was able to get it in with the two bolts closest to the firewall top and bottom but it doesn't seem right. the bottom front bolt hangs below the frame and the angle doesn't seem right to the steering shaft. Took some pics to help you guys visualize it.

Some pics of successful installs would be appreciated!
