67 Splash Guards? For 67 Barracuda Convertible

My 67 Barracuda was completed disassembled a year or 2 ago. My very knowledgeable mechanic that was doing most of the work passed away recently so I am trying to figure out where some things go. I have these 2 plastic things that each say LH and RH. They must go somewhere in the forward fender area or suspension just below the frame. I can’t figure out where they mount however.
Thanks for any help.
