Thanks for your response since our Bolers were "born" at the same place.
I have attached a couple of more photos of the tailight details showing the housing with the aftermarket lights
removed. As you can see there is no cutout for the standard tailight assembly. If one looks closely you can see a circular outline etched into the fiberglass at the bottom of the housing photo and at the top of the more close up photo. After cleaning off the oxidation this outline in also evident on the other side tailight area. I guess I will just have to stay with the box like assembly or go through the hassle of actually cutting out the holes
and trying to find the right fixtures. Does anyone have other ideas?
Thanks for all the feedback. Perhaps I will just keep it as an "ugly duckling".
