What are you looking for, quantity or grade? Any dexcool coolant in a 50/50 mixture will be just fine.

Might want to double check that. A quick googling shows that GM didn't start using DexCool until the '96 model year.

I believe that DexCool will work in all gas chassis no matter when it was manufactured. You just have to make sure that the cooling system is completely flushed when changing from the older green stuff. Yes they don't mix at all. My son in law found that out the hard way on his truck a few years ago. If you are just adding and don't know what you have? Prestone makes a 50/50 that is compatible with both. It states it right on the label.
