FMTV center troop seats

[Gunzy]

Does anyone have a picture and information regarding the rear center troop seats? I am picking up 2 NOS kits that are listed as "Troop Seats, center" for FMTV. Part #
57K2092 NSN 5240-01-560-4317. I can't seem to find any pictures or info other than the manufacturer and GP pictures of item. Any help would be appreciated, thanks.

Only time I ever saw anything like this was in the back of some M939 series at APG during LT school. They honestly looked like they were manufactured there, which wouldn't have been surprising since most of the ordnance (and thus, allied trades) MOS and NCO schools were on that base at the time.
