Hi all looking for what seems to be a 1980 specific part, it’s a bracket (PET calls “retaining bracket”) that holds the crankcase breather hoses at the rear RHS corner of the CIS assembly, as viewed from the rear of the car (facing the engine bay), please see reference pic and diagram from PET
I have two 1980 CIS set-ups and yet somehow am still missing this piece

If you have a spare you’re willing to sell please shoot me a pm.
Scammers don't bother, you'll be ignored and reported.
Thanks for looking!
