steering pump
 

hello, i need help figuring out which power steering pump to buy.
I have a 1991 supra with the 7mgte turbo engine. I'm trying to figure out if I need to buy the one with hydraulic reaction type pump or without hydraulic reaction type pump.
here's the link with both of them http://www.theautopartsshop.com/sear...s&anoFollow=no

I don't know if this helps but I recently got my power steering rack replaced and I got this one http://www.theautopartsshop.com/Sear...nd+PartDetails

any help is appreciated, thank you for your time
