Help ID 273-4 valve covers

Ok...now I'm confused on the 1967 covers...what side of the engine did Chrysler use the PCV valve on? The OP's first picture and the one Karl posted show the rubber grommet for the PCV valve on the passenger side cover WITH the wide wire loom bracket...but I have a 67 cover for the same valve but DOES NOT have the wide loom bracket......indicating this is for the driver side? I can post a pic, cover does not look modified....
