Anyone installed a poa update ? Did it help get colder ac?

I will replace a nonworking POA today on a 68 impala wagon.
I bet it gets colder than it does now.

Let me know how it works.

I know I wish I was making them.
$15-$20 in parts that sell for $95.
I don't care for the clutch cycling that the POA eliminator uses. I'd prefer a thermostat.
It does work though.
Youi COULD remove the innards of the stock POA valve and add either a Clutch cycling switch from an 80's-90's GM AC system on the R12 fill fitting and add a R134a fill splice in the #12 suction hose.
OR Clear out the guts of the POA, renove the R12 schrader valve, screw on the R134a fill fitting, and add a Thermostat to the evaporator. the thermocouple needs to fit in the Evap fins. Its an easy install too.
Either way would run about $40

Any way the wagon does blow 38* air on High fan.

Not bad. I am waiting for mine to arrive. Cant wait to put it on.

Got the POA update kit from year one (could have saved about $30.00 direct from old air products) just need time to evacuate the system and install it . Maybe this weekend.
