It will vary with the judging body involved. IMO original production line parts in mint condition with all of the original and correct part#'s and date codes, etc. will ALWAYS have an advantage over anything else in an OE judging situation (OE being original as it rolled off the assembly line).

Some will mix words, have varied opinions, attitudes, etc. but the bottom line is that calling anything short of the above description "correct" would be a contradiction of terms, and be an attempt to change history.
