Ok, just pondering this thought and looking for pointers....
I found a brand new ram-cylinder at a garage sale that appears to be very similar to those used in the Rock Ram steering...Could I get by so easy by installing the ram down below on the linkage, and plumbing the two lines into the existing power steering lines of my stock power steering to assist the ram? Or is a new power steering box needed as the Rock Ram kits calls for...If this could work I would be looking total cost of around $100....Much cheaper then the Rock Ram! Thanks, Johnny

i dont have any experience with them but it seems to me that in the kits they would have to be valved in such away to insure they always move exactly the same otherwise it would damage the box or linkage. why not just ditch the box and go fully hydraulic? unless you drive on the street alot in which case im sure that would be a bad thing

You need to tap the box in the two areas of pressure access for each direction of travel. Route lines from here to the cylinder. Problem with a stock Toy pump and power steering box is there really isn't enough pressure/volume to drive both the box and the cylinder well. Most aftermarket kits include a mod'ed pump to increase pressure/volume.

Search the General section threads for homebrew solutions people have used.

You should probably think about a bigger resivoir as well, since turning to full lock, where the ram is full pf power steering fluid, would probably come close to running the little Yota pump dry.

I called MileMarker when I was looking for a winch, and asked them about one for a Toyota. Their answer was that the Toy pump puts out 12-1500 PSI, and most american trucks run much closer to 2000 psi, so the winch would have a much lower max capacity. Just a little tidbit for you.

Also, I would definitely be in the market for a power steering cooler if I were you...</font>

Good info Camo....thanks.

When using a double acting cylinder, volume of fluid in the cylinder
is close to constant except for the space the rod takes up on one side
of the volume.

So the verdict appears to be:
Either one big friggen headache or one big friggen wallet. Neither of which I chose to deal with at this time....Thanks for the input all. <IMG SRC="smilies/biggrin.gif" border="0">

You could try running a Subaru XT6 pump... electric and variable, mount it on the fenderwell. Unfortunately I have no pressure specs yet. I paid $20 and plan to use it with a Milemarker.
