Simple it welded in 2 brackets in the rear, then bolted 2 bucket seats to them and carpeted the bed. What did this mean, well it was no longer classed as a pick-up oh no, now it was a passenger car!!!!! Job well done.
To be fair I quite like the look of then, lethal? yes, crap in the rain? yes (unless you've got the bed canopy), cool as a penguin in the middle of winter? most certainly yes.
