Ooooh, if I may ask, where did you get your new tail light housings?
They are from Layson's. Another repop that I had some issues with. I was gonna post some pics eventually.
I ordered these at the same time I ordered the trunk panel and Layson's painted the inserts black for me so they would match.
As you can see in the pics, the little trunk panel inserts are smaller than original and they leave a gap when you install them.
This support post? is behind the trunk panel inserts and it was too long so I couldn't install the insert. I had to cut it down and also decided to pre-thread the hole. The screws are meant to be self-tapping but I really hate using screws like that into pot-metal. It takes a lot of torque to screw in and I am afraid of breaking a screw or the piece itself.
So a bit later after I installed them into the car, I noticed that one of the tail lights was sticking out a bit too far so I went in to tighten it down and realized that the housing had separated where it is not meant to so no matter how much I tightened the nuts, the tail light was still sticking out.
The little posts failed and didn't hold the two halves together. I was cautious when I installed these and I was careful not to overtighten the nuts.
I took it completely apart and then put JB weld around the edges and clamped it together for 24 hours. Afterwards it was plenty strong and allowed me to tighten the nuts down firmly so the tailight isn't sticking out anymore. The other tail light doesn't have the same issue but I may proactively take it apart and then JB weld it back together like the first one.
