Technical Question for guys who've installed '39 taillights in Model A

here's mine

 

Yes they are equally crooked, you are one talented SOB

 

Talk about mixed signals, I hand signaled left,, my grand kid thought I was getting rid of a booger.

 

This is exactly the steps I have been looking for, thank you!

 

ok maybe not 39 but this panel was from a 28 model A . Light holes and rust covering done by a drunk blind monkey with his hands behind his back me thinks??
