As of this date AutoZone has it in their house brand. Part number A003.

NAPA has it in their house brand. Part number NAF1GAL. The NAPA near me also has the Zerex brand. Part number ZRX ZX001.

A local independent auto supply stocks it because they want to support the classic car market. It's labeled FVP Original Green Formula. Part number FVPGreen-Gal. It's distributed by FVPparts.com.

You want to only use the green coolant. They have it at Napa and it meets 1825M GM Spec.

For Zerex the first gallon is called Regular Green Coolant (GM 1825M), the second gallon is called Original Formula (GM 1825M). Zerex ZXRU1 is 50-50 and Zerex ZX001 is undiluted. The third gallon is NAPA coolant (GM 1825M).
