Pics of bed cross sills???

[terd ferguson]

This is for a '55 2nd Series short bed step side. The old bed I took off was jacked. It had delaminated plywood for a floor, rust holes, and missing cross sills. I built another bed out of better parts. I'm not quite sure exactly what else I need to mount the bed. Maybe you guys can help. Pics of all the cross sills in place without the bed on would sure help a ton!

I have one of these (rear cross sill)...


and one of these...


I think I need two more of these?...


And is there one under the front panel???


Thanks for the help!!!
