For a 78 K5 Blazer the GM parts manual calls for a 1977026 - rotor D433. On rock auto it shows a ACDELCO D468 or ACDELCO D448X. I'm not sure which one to use and how they are different. Thoughts?

The difference between the Rockauto parts could be the actual manufacturer, contact material, etc.
You’ll need access to superseded part number info to know which is a direct replacement to your number.
