Replacing the LM358W Operational Amplifier in the CP Control Circuit

Hello!
I'm working on building an OpenEVSE Controller using data from GitHub (Eagle) for personal experimentation. The OpenEVSE_PLUS_v4 circuit uses an LM358W operational amplifier in the control circuit for the pilot signal. However, the LM358W has a service temperature range of 0°C to 70°C, which is unsuitable for my application in colder conditions (-25°C to -30°C).
I found the LM258DT operational amplifier, which is rated for temperatures down to -40°C. However, I need to consider alternative options. Can you suggest a suitable operational amplifier that can replace the LM358W and operates reliably in temperatures as low as -25°C to -30°C?

Additionally, please assist me in finding such a component available from this online store: https://www.lisleapex.com/product-lm358wdt
