92-99 K1500 Suburban - A/C System Part Number Evolution

Accumulator fitting angle idea appears to be correct, the external otherwise looks the same.

For condensers: 88-93 has no high pressure switch fittings. 94+ have a port for the pressure switch, and otherwise they look the same so it's probably a fitting size difference across the years. I read on another forum that 94 and up the fittings went to metric, but a guy on here has a 1990 with a condenser that has a high side port on it (indicating 94+ model) and it's all bolted together so I'm not sure on the fittings.

My 90 i swapped 94 parts into
