second row captain's, how are they mounted

[Moreforles]

I have a 94 and the seats are mounted (snap in, I think, but I've had the seats out for at least two years) there was a steel plate under each seat that's bolted to the floor with four bolts (threaded into the floor, not a bolt through the floor like on full sized models) I actually took the plates out last week. not using the second row buckets in this van - still hoping to turn it into a small rv of sorts....
