69 Barracuda Reverse Lights

My Barracuda is the gift that keeps giving.:banghead:

I have owned the car for two years and been slowly working my way through all the bugs. This weekend is the nonfunctioning reverse lights. As I pulled them apart I found there was no socket or bulb. I have a few questions for the group:
1. Where can I get a correct 69 lens and socket for the reverse lights? Repop is okay.
2. My assembly manual states the correct bezels are a part#2930 618-9 or 2930 810-1, the bezel I have are part#2930 620, but the bezels look correct?
3. What are these strange looking lenses that are on my reverse lights?

Thanks,
Andy
