Sorry I didn't see this thread earlier, as I have experience with both the bezels and repop tail light lenses. I had a pair of original bezels restored a while back by Special T's. They look excellent. I had searched around for a while to find a pair of nice cores, the less pitted the better if you are going to have originals restored!
I bought one repro tail light lense 4 years ago from Pentastar productions. I don't know if all repro lenses come from the same source? Usually that is the case, someone repros a part and all the places like Y.O., Paddock, etc just source the part from that manufacturer.
I paid around $100 for the drivers side lense, and initially I was pleased. But then one day when I was sitting behind my car at a car show on a sunny day I noticed the repro lense was lighter in color than the original I had on the other side. If you are installing a pair of repros this issue would not be that big a deal I guess.
The other problem I noticed was that the repro wasn't quite correct dimensionally. When installed there was a small gap near the bezel next to the reverse light assembly. Because of these two issues I searched until I found a decent drivers side original, polished it up and installed it, sold off that repro lense and am happily driving around with my car all original now!
