Jeff,
plz tell me are the pics with the original taillight body underneath and is this the final position of the taillight ? Did you use the rubber gaskets ?
Seems I can look a bit "behind" the chrome ring. I´m in the process of fitting my 50 pontiacs and I want them a bit deeper down the opening. The bulb housing of the pontiacs seems to clear the stake pocket, guess I´ll have to cut the edge of the rubber gaskets ....
Thanks, Tom
