Responding to thread topic (I did not read all the posts). Best I can tell, OP is converting from R12 to R134A. From the photos, it seems the original R12 condenser is being utilized. I also see a POA update tube has been installed. While this setup may work in milder northern or west coast environments, it won't work well when temps start to climb above about 90 degrees F. The R12 condenser just is not efficient enough at shedding the latent heat from the R134a refrigerant. An electric fan would help and should be considered a must. problem is, there is not enough space to fit a fan between the condenser and the hood latch support structure.

In my experience, the POA update kit is junk. You will feel it (air temp) every time the compressor cycles on/off which will be often.

Good luck.
