1983 AC Lines

[Kilian]

Hello, I didn't want to hijack the other thread about AC lines, so here goes. I've got a 1983 GMC with a 350 and the old A6 compressor. Looking for part numbers for the AC lines from compressor to condenser/evaporator and from condenser to evaporator. I don't have original lines, as I'm adding AC to the truck.

I've looked through the parts catalogs, but since I'm not sure when the A6 to R4 change was made, I'm not sure if the hoses listed for 1983 would actually be what I'm looking for. I was going to use what is listed for 1980, when I'm pretty sure the A6 was in use, but the condenser is different. Picture is of the condenser that I have, which I think is 1983 and newer?

Are you adding A/C to a truck that had it originally? If you have the A6 already, where did you get it? The rebuilt ones don’t seem to hold up very well.

You might want to also look at upgrade kits that replace the A6 with a Sanden or Seltec compressor. Lighter compressor and much small mounting brackets make the fitting easier. There is also the Pro6Ten compressor, which is a Sanden compressor that is repackaged and made to directly replace an A6 (uses original A6 brackets and hoses).

Try looking at ackits.com, Arizona Mobile Air, coldhose.com, oldairproducts.com and other suppliers to find what you need. Many of the compressors and hoses are also sold by Summit, RockAuto and other sources, and may be cheaper from those high volume sellers.

I'm adding AC to a truck that didn't already have it, so don't have the original hoses to match, etc. Went with an A6 as opposed to the R4 because of reliability.
I'll take a look at the companies that you suggested for what might work.

You might find just buying a kit from vintage air is your best bet. The firewall is different on a non-A/C truck, you need brackets, pulleys, etc. Then you need to figure out hoses. Buy a kit and your life including getting spare parts is much easier.
