Correct cap & rotor: 87 350tbi

[Dave87]

As the proud new owner of an 87 Siverado 350 tbi I am starting to collect tune up and repair parts. I have found that the original AC Delco dist. cap is probably a D303A but I find 2 rotors listed as oem: D470 and D447. Anyone know which is correct and what the difference is? Anyone prefer another brand for these parts?

Only difference I can see is that one is price. either one will do just fine.
