The AMC-era Wagoneer should be passenger side drop and 6-lug. The Chrysler-era Wagoneer should be driver side drop and 6-lug. When disc brakes were added to the FSJ in 1975, there was a switch from 5-lug (drum) to 6-lug for the 1/2-ton.

Baldy used the coils and DS drop D44 from a 78/79 F-150 and swapped on 6-lug outers. Look up his posts on the subject of his D50.
