Part number help PLEASE!!

87 IROC Z 5.0 TPI, does anyone have the “new” part numbers for all 3 relays ( MAF, BURNOFF, FUEL PUMP) which I can get in O Reilly or auto zone? I had one recently and can’t find it to save my life..looked up what I did find and it was like “ac comp” relay or something. I’m replacing all three, anyone know what to ask the parts store for? They can’t find anything using the original GM numbers.

Just curious, so if nobody knows part numbers, What are you guys using when your relays fail?

Go to rockauto.com
Find your thing.
Don't buy the cheap one.

This strategy will likely assist you in future stock part replacements. Standard Motor Products has been a reliable brand for me when AC Delco is not available.
