something to remember if you are wishing to put those front garnishes on your 71, the 74 has side markers (guard mounted indicators) on the guard itself, whilst the 71 has the side markers on the actual corner garnish.
to stay legal and keep the upper indicators, you will need to either swap the guards from the 74 onto the 71, or drill the 71 guards to fit the indicators from the 74.
hope that helps.
