Part 2:
The new headlight assemblies require some modifications (trimming) to fit the Beaver.
6) Picture 06 shows the brackets installed (there are two plastic retainers on each side of the housing. The aluminum brackets slide into the retainers then a second aluminum piece sits on top of the first preventing the bracket from sliding back out).
7) The first piece to be trimmed is on the inside edge of housing. The stock headlight housing juts out on the inside top edge. This part needs to be cut off so the entire inside edge is flush to lens. I used a hacksaw, then fine trimmed with a dremel tool. (Picture 08 and 09).
On the other side of housing, there was a cover that fits over bulb that I need to trim one rib off of. it was barely touching the edge fiberglass hole in the coach body preventing the headlight from fitting in. (Picture 10).
9) Lastly, I had to trim the black plastic "wing" that sits above the lens. I used the dremel tool to cut this off flush with the top of lens. (picture 11).
10) With all the trimming done and few test fits, I was able to reinstall. tested all lights, then remounted AC evaporator.
Left side done - I expect right side will be easier to remove since there is not an much in the way. then just do the same trimming as needed on the other headlight.
