I would say yes...The mopars from that era should have the mercury switch it was quick and simple to add on the assembly line...The shape and/or size of the unit,bulb and/or connectors might vary...Check out this auction for the 74 monaco trunk light...The unit looks pretty close at a quick glance except for the harness connector..
LINK Here's a pic of the E body piece submitted in a previous post..In the E-bodie's case this harness acts as a jumper...Unplug the already present harness connection near the left trunk hinge and plug in the AO1 trunk light...
Those harness connectors are used at other locations on the E-body so you could make one up if you had the bulb/switch and some spare parts around for the task..
