you could get the serpentine belt conversion kit. IMO if you have the money for it, it would more than benefit you.its about midway down on this page:http://www.zsimports.com/Mechanical/index.htmand will run you $425.00
There's only one part # and the water pump pulley is only different with p/s or without.
anarchyx34--On that EKTA diagram, is that for a 1991 NA w/ AC and PS? if so, what is the part number for the two allen (8mm) bolts which keep the AC Comp. in place when tightened and allow the unit to pivot when loosened? Hard to tell exactly from this drawing.Anyone?
