Jump Seat Frames from '78 Datsun/Nissan extended cab pickup
Same as dealer option in '80-86 Broncos. Upholstery was ruined, but is easy to reproduce.
I'm still not sure if these were a factory option, a dealer option, or an aftermarket option. I've only seen 2 other FSBs with them, and both were '80-86 with matching upholstery, but that might have been custom-made. I know they were original equipment on Datsun/Nissan king cabs.
They're surprsingly comfortable & secure, according to everyone who has ridden in them. Even the ones who rode here during some ROUGH off-roading.
The biggest DISadvantages to these are that I can't use an aftermarket molded cargo area mat, or the stock '92-96 bedwall panels because of their pockets. They won't work with an inside spare, either.
