Front park/side marker light

Hi , Yes I searched , but still can't find a defined answer. I had a real weird thing happen on the way to work 2 months ago. It was snowing hard and visibility was poor , then I saw a yearling
moose standing on the road. I was going 25mph but couldn't completely stop. The moose would walk one way then the other , side to side as I approached. I " sideswiped " the moose at walking speed and narrowly avoided going off the road and down a 35' embankment. I need to replace the left side marker because the mounts are all broken. There seems to be different lights made for a 4X4 and a 4X2 truck , is that accurate? I am good with an aftermarket lamp assy. but don't have confidence that what they offer will fit my truck. Anyone had some real life experience / recommendations on lamps? Thanks ! OEM seems very expensive for what your getting.
