I actually have 2 questions? I own a 1992 5.0 LX. Recentely my power steering pump went out. I have decided to eliminate my ac and was wondering am i supposed to puchase a power steering pump with or without ac? I purchased the one w/o ac, but am wondering if it will work? Also, I have removed the power steering pump but cannot get the pulley off? Any suggestions would be great. I tried putting the pulley in a vice and loosening the bolt, but nothing? Any help would be great.
