looking for these;i need the 4 brackets that hold

The all aluminum plug wire looms.I have these B.B-Looms in great shape,If i can find a set of these or where i can get them it will save me $80.00 -shipping probably. They are small-- one 1/4" hole in the corner- and a longer- slotted tab--hole-on the [side]
for adjustment-- This appears to be a 90 degree bend ,one side longer and slotted with 1/4" hole in the corner. Maybe you may know, if you don't who may have a set of of these.I described it twice i know-- but that was so i could get the idea in my head better --of whats needed. any help i am grateful bob s
