If I remove my spare tire on my '36 5w is there a licence plate/light bracket I can bolt on to take its place?
Whatever bracket you end up with, I have found it best to make a plate of steel the shape of your plate to bolt to the bracket. This gives the ability to fasten all 4 corners and avoids having the plate flap back and forth going down the highway and tear when only mounted from the bottom.
I've got a brand new one that I was thinking of selling - PM me if you're interested and I'll take a couple of pics & send them to you.
