Frequently Asked Questions

How many vehicles does ACDELCO R45S fit?

23 Year-and-engine configurations from 1954 to 1970. Each row is one published application — year, make, model and engine.

If my vehicle is in this list, is R45S guaranteed to fit?

The row means the manufacturer published fitment for that year, model and engine. Still read the notes for position, trim or production-date qualifiers before you order, and cross-reference the number against the part you are replacing.

Can I jump from this list to the parts for my vehicle?

Yes. Each model link opens the matching category page for that vehicle so you can compare other brands that cover the same fitment.
