Drive down from Ohio to say Houston, Texas this July. Spend a couple of days there driving around in stop-n-go rush our traffic. After that, head west to Phoenix, Arizona and do the same.
Check back in here afterwards and let us know how you feel about R-134A in your 126.
It may work in Ohio during the summer. Few if any who live in REALLY hot climates have had anything good to say about R-134A in a 126 car.
