slide-out switch nightmare

I do know that I have a hydraulic pump/reservoir in the right front outside cabinet above the batteries. I know two of the slides have rack and pinion drive. If I am to move the slides manually, I will have to fabricate a pipe with a slot for a drive mechanism. The tool on board to manually operate the front landing gear would never fit where I would have to operate the rack/pinion mechanism. More investigation needed on my part. Thanks to all for your comments. I'll keep you posted.;)
