The rear turn signal bracket for many models is one of those parts that remained virtually unchanged from beginning to end.
This bracket is an improvement over the original in that it is made of polished stainless steel rather than chrome plated steel, so it will essentially last forever.
This part is a quality reproduction of the European version holder which is 37mm ( 1-1/2") shorter than the US version. This one is 325mm long, whereas the US version is normally 362mm long to meet DOT requirements.
