Does the Dakota P/S us recirculating ball or is it rack and pinion?

Thanks!
Forgot to mention that the power steering unit got installed into the Durango. I figured that, since we were travelling to Oiho in the Durango anyway to go visit family, and that I'd have a lot of time on my hands while there, and while the Durango has approximately the same engine as the Dakota, I might as well test the installation on the Durango.
I don't know exactly what the flow numbers are, but I can tell you that at idle, and with 16 fluid ounces of fluid in the reservoir, the pump will empty out its reservoir through the gear in about 3 seconds. That works out to approximately 2.5 gpm. I didn't really accurately measure the time, though, so YMMV. The MR2 manual states the pump should develop at least 711 psig at full lock. Other than that, there's not a whole lot of information on the intertubes about this pump.
Both the Dakota and the Durango use rack and pinion steering. I would think that your recirc ball setup would perhaps feel slightly sluggish with this pump. I know that the Durango occasionally has a slight amount of lag, usually when coming to a stop after decelerating. It may have something to do with the fact that the Durango (and the Dakota) outputs a VSS that is 8000 pulses per mile, and the the pump only expects 4000 pulses per mile.
