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.

Usage Codes:
A/C = Air Conditioning
A.I.R. = Air Injection Reactor (Smog Pump)
EXC = Except
FR CR/SHF = From Crankshaft
GEN = Generator (Alternator)
H4D = Spring Actuated Emission Control with Cast Iron Exhaust Manifolds (Heat Riser Valve)
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
