Hi all,

I'm trying to gather intel on how the air conditioning was set up on the first gen trucks. I'm looking to piece together a system for my truck, as I'm living in east Texas currently, and a/c is virtually a must. At the same time, my truck is in good enough condition that I'd like to keep it as close to 'stock' as possible, which means that I'd like my a/c to look like it was put there by the factory, or at the very least, by a dealer. What components belong in the system? Where should I look for the compressor, condenser, expansion valve, heater core, etc? Where were all of these components mounted? I know that my truck having the 4d55 will make a small difference. Finally, how well will these components deal with the transition from r12 to r134?

Thanks,
Ryan
