Purchased a atail light from a fellow forum member and it has this bracket on it that I cannot use at this time. I posted a thread to try to ID it and it is here:
late brass bare bones car with demountable steel fellow wheels?
Anyway, if you need one like this, I'll take $25 plus shipping and get it out to you. No model number on it, but Ford script stamped in the rear of the bracket. A little twist to it that can be straightened out if need be with a little heat and a little hernia.
