V-Belts and routing 85 C30 5.7L w/AC

[zieg85]

The fan belts on my 85 C30 are wrong.  I think the AC and PS belts are on wrong and I think they are reversed.  Does anyone have the belt routing and sizes for the AC and PS belts.  Thanks in advance

I got to looking in my book and came across these.  My RPO sticker says it is a LT9.  What does all the abbreviations mean.  All I have is AC PS/hydraboost and alternator.  HD emissions so nothing else on it.

P/S = Power Steering
P/S/B = Power Steering / [HydroBoost] Power Brake
W/ = With
W/P = Water Pump

The LT9 in my 1986 K30 took the following part numbers, they also go on in this order if I remember correctly:

AC Delco
15400 - Power steering pump
15555 - Power steering and AC
5K435 - Alternator
15440 - air pumps
