I bought a parts BII years ago. It was an 85. The only thing I regret now is not pulling the rear bucket seats. They were lumbar seats also. I've never seen another one.
The bucket seats were themselves not special, what was special was the sheet metal brackets that the seats were bolted to.
they were fairly simple brackets because they had no provisions for the seats to be adjustable.
The tumble-fold feature of the bronco2 is overrated, cargo capacity?
Beyond a load of groceries how much room do you really need?
My issue was that every time I ever sat in the back of a bronco2 it was a cast-iron SOB for me to get out of the folding seat.
The seat bottom isn't latched down and tends to "tumble" forward
as you try to get out of it.
Frankly I'd put highback seats (gen2 ranger or early explorer)
or seats with headrests (Ala' Turbocoupe or Mustang GT)
in the back.
Yeah, "lumbar" seats are nice but seats with Lumbar AND adjustable side bolsters are even neater.
