In addition to Joe's suggestion above have you thought about buying a repop tail light assembly for the right side? I run two original styles. I did paint the inside of the housing with crome paint to give better reflection and it did. I also went 12 volt. Just a thought on the right side taillight.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
