Front windshield trim - older foxbody is chrome, newer 87-93 is black. I believe you can put the trim from newer models on your 79.
Second pic shows 87-93 tail lights already. To fit right and seal, you would need to change the metal tail light panel as the openings for wiring and light bulbs are different. If the picture is your car and lights bolted on, you are all set. If lights are just sitting there, you can see this yourself, just look at the tail light seals and the opening in the metal. 83-93 use the same tail light panel openings, 79-82 are the same.
Third pic, you are looking for Outer Door Belt Mouldings

The upper two are the outer trim pieces, the bottom two are the felt/rubber window seals. These parts are listed as 87-93 but I am pretty sure I have used these interchangeable with older foxbodies (it has been almost 30 years since I did it so the memory is not that good). Best bet would be find a foxbody at the wreckers and pick up these piece to test fit. If it works, you can buy new.
