so I have grown tired of not having a/c in m 1970 impala. living in Texas, makes it near impossible to drive for over half the year without a/c especially with vinyl seats. I'm having problems finding the exact equipment I need, I have looked to find a kit maybe with all the parts I need. Also...

Does anyone know off hand what size the NPT fittings which go into the Radiator are? from a Powerglide. I'm looking for a die, to clean up the threads on the line fitting. Thanks, Nacho65SS

The passengerer vents on my 03 Impala are great for my passengers. But on the drivers side, they blow warm air on me for about 30 minutes - the length of my commute. It didn't do this last summer. Help!!! I live in Arizona and it's scorching here!
