I am retrofitting AC into my 82 RC.  It is a 318 truck that was built without AC.  I grabbed the AC compressor, all the brackets, and the pulleys off of a smallblock Dodge van.  Except the power steering pump brackets.

Looking at the brackets and pulleys before I start the swap it appears that the old pulley for the P/S pump will be occupied by a belt for the AC compressor.  Is this true?  Rockauto lists the same P/S belt for AC and non-AC applications.  I have far more experience with slant sixes than with V-8s, so I don't know offhand if adding AC will require changing the power steering pump bracketry as well.

Can anyone confirm or deny whether adding factory AC brackets and compressor will require changing the non-ac PS setup?

Thanks.

I know my 1980 motor had ps brackets towards the top drivers side of engine, and there’s another bracket setup that moves the ps pump to the lower drivers side.

Now that it’s in the lower position, I can see the timing marks easily.

I know where you can get a new setup for about $110 for the lower position brackets, but I would think the lower position setup is specifically for the ac model engine s.

Yes, the stock brakcet on my 82 puts the PS pump almost directly in front of the driver's side cylinder head.  However, the van I got the AC stuff from also had the pump there (if I am remembering correctly).  I hope I don't have to find another PS pump bracket.

My 1983 Dodge parts manual only lists one PS pump mouting bracket setup and doesn't differentiate between AC or non-AC applications.  I guess that answers my question.  ???

The power steering mounting position is not important. There are different pulleys for the A/C and/or 114 Amp alternator and non-A/C and 60 Amp alternator. Keep in mind that both A/C and the 100 Amp alternator setups require dual belts.

Non-A/C:



A/C and 100 Amp Alternator:

Thanks!  My truck has power steering but no air pump.  The only brackets I could find were for AC and a 114 amp alternator, so I am upgrading my charging system at the same time I am retrofitting the AC.  I grabbed everything from the sam evehicle- 114 amp alternator, alternator bracket, and AC compressor and bracket.  Pluss the water pump and crank pulleys.  And the belts.
