I don't know what a 'bood' is ,
But there are rails bolted to the floor originally for that seat.
It's kind of an odd setup too, not exactly what you'd expect.
The 'trick' is you start by undoing the aluminum trim piece across the door
opening. 

I have some untouched in an 85 GL. These rails and special fasteners. 
If you take them out without taking a picture, or making notes, or having
another van to look at, how they go in isn't so readily apparent.

Subject: Middle seat in GL

Okay so I bought the great 86 GL with the bus type seats. The center seat is
bolted in. They used the area originally for a wheelchair, so the floor has
bood and rubber floor over the original carpet.

Recently an email here said the middle seat "slides" in.

Is there a frame missing that the middle seat slides into?

thanks,

Janet
