Name that part and you get....well you get a pat on the back

Been Waaay to long since I have disassembled the Duster so need some assistance.

Can't remember where these went, black plastic with 2 metal clips each.

The Blue part I posted on the forum a year or so ago and stumped everyone maybe it will catch someones eye this time, it is stamped steel threaded in the holes and by the dirt/dust on it I would say it was exposed to the outside somehow.
