Probably the best bet.
When I lived out there I only saw one early '70's FSJ truck, in all the yards I went too, years ago at the pull a part near the Akron Fulton airport. They tagged it as a Comanche
Can't remember but the yard in Burbank ( near Lodi Outlet mall) had a couple of old Jeeps. Couple flat fenders, CJ's and an old Willys truck. Maybe a FSJ hidden there.
