#18 - Yes, it's a Custom Cruiser. Can't really tell if it has the silver cover over the C-pillar, I'm thinking no, which would make it a 1986-87.

#19 - Has the 1981+ taillights. 1981-82 were Marquis, 1983-85 were Grand Marquis. I can't make out the badge.

#24 - Looks like a Mitsubishi, either a Mighty Max or early Dodge D50/Plymouth Arrow Truck

#28 - Looks like the 1987-88 taillights
