Parking brake retainers

[keith808]

Please see the pictures included.
I am trying to find these retainer clips for the cables to lock into the backing plates.
I got new correct year "supposedly" rear cables from classic parts but they look different.
I have checked 4 different sites and no one has any retainers other then Brothers trucks but theirs looks like you would have to drill 2 holes.

DO you guys have any suggestions on what to do to retain these cables properly?
Does anyone have these parts or know where I can get the proper parts even if I have to buy another set of cables?

Thank you
Keith
