huckleberry, glad to hear your finished with Chemo and Radiation. Sure hope, and pray, all goes well from now on.
Since everyone doesn't visit here in the Welcome Centre your question will be best answered in the sub forum for beds. I think its a sub forum of the paint and body..or just below it. You'll find it and also a link to Mar-K.
I will comment that as for the bed placement it may be good for you to check out Mar-k. They have a link here and I think you can see, or get, a pictorial of how the bed goes on.
I had one years ago so I'm not sure anymore....but there are cross sills that go across the chassis for the wood to lay on and "generally" the boards are held down with metal strips that have the square headed bolt hole's that the bolts drop down through between the boards.... that is how I remember it...and basically how my 37 bed is on my pickup.
