Rear tail light bezels are avail thru BEA .
Although I have not seen them installed so I can't comment on fit .They are not without there flaws. I've seen them in person, and to me they look like redone bezels. The edges are real rounded and soft making the curves.

Rear finish panel is avail from Metro
Same deal, it looks nice but will not pass for an original to anyone who knows the 69 GTX trim.
On the car the 3 pieces may compliment each other very well though. And will most definitely brighten up the back of the car.

Metro side trim is nice, even though the exterior dimensions are ever so slightly wider than OEM. Same deal anyone familiar with the 69 GTX specific trim will catch it they are repops rather quickly. I used them on my former GTX vert and was happy

Metro wheel lip mdgs I can't comment as I've not seen them on a car( my car had originals) , but they look good in your hand

Overall I would say use it all as it will be a big improvement over most any used stuff
