A/C Conversion questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

chevymaz · 11-20-2005, 08:48 PM

I started putting the A/C back in my 71 GMC today and found out the compressor is locked up. I am also missing the condender, dryer and the POA valve. Will a later model compressor and condenser fit? Will I need additional brackets? Should I go ahead and convert to R134A? What model trucks should I be looking for to get replacement parts from?

Thanks in advance

Greg

I would deffentally go to R134a now, becuase R-12 is REAL expensive and it is only going to get more and more.
