[Chevelle-list] A/C Question...

[bad66chevelle454 at aol.com]

Has anybody ever converted thier R12 to R134A?

I have this 62 Cadillac that has A/C. I thought it might be neat if the A/C worked on it. I have to convert it over to 134A right? I'm assuming that there is zero refrigerant in the system right now. I've done a little research on it and it appears that besides vacuuming out any remaining R12, I need to change the compressor oil? The compressor spins freely, and smoothly. I have zero A/C experience. Do I need to change out anything else? 

Thanks for your help!!!
