To "B" body, or not to"B" body

[mtbase]

I' looking for help on identifying these brackets.
My 66 Coronet 500 came to me in boxes, buckets and bags, I'v spent the last 4 years finding just where they all went. There's not too many pieces left, but these.....
I've always suspected that they were sway bar related, fortunately another member showed me the way the front sway was intended to assemble/work. So these remain homeless unless someone can educate me. Perhaps they don't go to this car at all.

Any help is appreciated
