- 1971 Riviera
Sorry to ask such an elementary question, but does anyone have a list handy of the common ACDelco replacement parts for a '71 Riviera coup (not GS), 455 4bbl. For example, spark plugs: R44TS; oil filter: PF24, etc., etc. Does such a thing exist? I get multiple options on the ACDelco website when I go by car year, make, and model, and it won't work for the VIN b/c it is only 13 digits (requires 17). Thanks very much. Hope everyone is well.
