You are correct on the battery I bought, the tag on the battery says it is 770 CCA and required no spacer. none seem to have the vent kits. My car had the Mopar battery, so it was probably installed after the car was built. It had never had a problem, but I know it was over 3 years old. It's gone now.
Does anyone know where to buy the tubing /fitting to build the vent kit and collection pot?
