From what I see in all the photos I see on line, the Mopar non-LED headlight assemblies (different for right and left) consist of 8 parts - 1 bucket (black plastic part immediately behind the headlight housing) different between right and left, 1 housing (H13), 1 bulb (H13), 1 bezel (different between right and left and 3 screws to attach the bezel to hold the housing in.
No picture I have found other than the one posted by OP, shows the rear attachment which attaches to the radiator support, yet the radiator support listing does not show that part either. However, I don't think that part is off a Jeep Wrangler.
I looked at this video:
In the video, the Quadratec tech is removing the stock headlamps and bucket from a JK prior to installing a pair of Mopar LED headlamps. At about the 1:30 mark he removes the left headlight from the bucket and then pulls the bucket off the studs on the radiator support. Note in the video, that the thick plastic part behind the bucket shown in OP's photo is not present. When the bucket is removed you are looking only at the radiator support.
One other thing I noted in OP's photo - that is an H4 headlight with the old three aiming tabs. Those tabs are not on the stock Jeep H13 headlight housing nor is there the fluting shown in the glass of the headlight in the photo. If I were to venture a guess, that headlight is an H4 connector sealed beam.
Bingo - the photo OP posted is for Mopar 55055032AF or 55055033AF which are TJ headlight assemblies. https://parts.jeepsareus.com/oem-par...eam-55055032af
OP - this may help your search. Note it does not have the adjusting screws.
