I have read that the steering shaft needs to be changed to add power steering, as the manual shaft is too long. Is there any reason, you could not just cut the shaft to the correct length and and sleeve weld it back together?
Thumpower, please share the info if you do this, and use the borgeson coupler. I would like to install p/s also. Was also thinking of trying an electric steering assist under the dash, even though I already purchased the OEM hydraulic pump, steering shaft, and box.
