Parts fisch doesn't show the collar as a separate part, or even show it in the pic of the entire taillight assy. I have one in front of me now, and from what little I can actually see, its maybe crimped on somehow. It sure is tight as well. I tried to pry it, twist, and pull in every direction, and couldn't get it to budge. Tried to "slide" it
upward, thought it was maybe like a clip on type thing, but that didn't work either.
Stumped as well
Is it supposed to just snap on, and the collar is lose for
whatever reason?
