The rack itself is a bolt in as long as you have the bushings and brackets from the manual rack, the only difference is the steering column intermediate shaft, if you find a manual rack at the junkyard just take everything from the intermediate shat to the tie rods. When I did mine the shaft was already gone so i just welded an extension onto the universal joint where it goes through the firewall. You can also disassemble your power rack, grind off the fluid plunger/piston, cap the lines and essentially have a manual rack without the bad steering ratio, after having both I prefer this method. I plan on doing a write up on this when I get back to the states.
