Thanks Matt
I got that same info from srswap.com and it is wrong. The A/C belt does not use a 4PK880 it uses a 4PK890 which equates to a 350K4. The 4PK880 (345K4) is too short and will not fit around the idler pulley even when it is adjusted all the way loose.
I am starting to think I received the wrong power steering pump here. I will have to check the part numbers for the correct non-HICAS S13 red top pump.
Thanks again
