The feature that is threaded which goes through the "Maxim" handles on either side of the rear fender is not long enough to thread a nut onto to hold it in place. I had to cut the rubber of the stem back enough to get the threaded portion far enough through to put the nut on. The end is not metal like the OEM it is rubber and much harder to get into the turn signal housing. There is a shallow hole meant to fit over a pin in the handles I refered to above on the OEM but missing from this part. It is to keep the signal from rotating... Just trying to save someone else the frustration and work that was had over what should've been a 20 minute job.
