Left caliper bracket 73+ disc

Wow, you know something after all these years with parts, i never paid attention to those caliper mounts, brackets, to see if there are any differences to them.
Guess there officially is a leftie, and a rightie.
I always had them in "pairs" and never looked that close with them.
I'll sell the pair to you, i won't break up the set.
That won't do me any good.
Interested?
