I'm going to try to get the OEM AC in my 68 GTO up and running again using R12 and original components. I've never done this before so advice will be needed. I'll be using the original A6 compressor if possible, if not then a new A6 unit from Alma.

Current status:
Have A6 compressor low miles original (needs at least clutch bearing)
Original Evaporator, looked great when I had it suitcase apart.
New OEM style condenser
New Drier (will still need to be replaces since I left the plugs out)
All the OEM suitcase related parts POA, expansion valve? etc.

Supplies and Tools
Plenty of R12
Robinair Vacuum pump
NOS Robinair vaccum manifold and gauges (made in USA)
3 charging hoses red, blue yellow from Robinair gauge kit
Purge valve made from a "T"
Scale to weigh tanks if needed.

My first task is to move some R12 from a 50 lb tank to a new 30 lb tank.
Here are photos of the tanks.

Full Tank


Empty Tank


Here are the hoses I have to work with.



Not really sure what hose to use. Plan is to draw a vacuum on the new empty tank, hook up a line to the full tank, purge the air from line and see how much I can transfer over without resorting to ice/heat.

That's the extent of my plan and knowledge at this point

Thanks
