leathermang: Thanks for the compliment, but I've always been better suited to being a bad influence than a positive role model. It is good to know I'm on the right track, even if it is a more expensive track. I plan on keeping this car for a number of years, so I feel like the best long term approach is going to include a r134a for future compatibility. I also see a Sanden in my future, but I will admit I have a prejudice against things that say Delco on them. GM's Achilles heel.

vstech: The thing about increasing coolant capacity is that you can only really use what you can cool. Having a "reservoir" of extra coolant on the cool side of the condenser would just give it time to warm back up before being used I think.
