Power Steering Fluid?

My PS system has a clear fluid. My rebuilt "Firm Feel" box has a clear liquid. The manual for 71 Demon says to use Mopar part #(obsolete). The chassis manual says to use the recommended fluid or one that will not harm rubber hoses.

Yes I could call Firm Feel on Monday ( its Saturday morning as I write this) but I was wondering if anyone off-hand had a fluid (not AT fluid) that they use? I'm probably only a few ounces shy of full and I am tempted to use my AW-32 hydraulic fluid to top it off. Thanks, would love to drive it today but if I have to, I can wait till Monday.
