You wouldn't happen to be in California...

The CA 134a cans are different. There is an adapter.

I'll be honest here.

You need to do something about your shipping costs.

$16 to ship to California is WAY HIGH.

Both those fittings look like they're for R134a hoses.

Is that what I'm seeing, or is it for both R134a and R12?

The 2 smaller fans may have more coverage area.

The 2 smaller fans will be thinner (more clearance)

With a fan failure, you'll only lose some of your airflow.

With 2 small fans, you can stage your cooling.

You may need to upgrade your alternator.

A 71 is only like 60 amps.

You could rewire it so that the existing wire to the clutch turns on a headlight relay that then gets it's power directly from the battery.

Say you have a single stage vacuum pump that can goto 100 microns at sea level. If you goto 18,000 ft, where the air pressure is roughly half that at sea level; can you get down to 50 microns with the same pump? The exhaust is only working against half the air pressure, so wouldn't the micron level ...

You can test the wide gap by giving the clutch face a tap with a hammer handle when the engine is running.

The tap will move the clutch just far enough for the electomagnet to take over.

Had to tighten up my gland nuts on my gauges yesterday to stop a leak. This made me think that shouldn't there be something between the seal and shaft to lessen wear and help seal the shaft (if there was any, it's long, long gone).... Is there some sort of vacuum grease that can be added that doesn'...

Is the mineral oil for R12 the same as for R22?

I have some 525 viscosity mineral oil for R12, can it be used with R22?

I'm having trouble finding specs on what mineral oil to use for R22



thanks
