Our '56 Safri has an approximate 3" radiused corner on the beds. The way it is done is with a 3/16" plywood which is steam bent around a 1x2 frame. I can post a picture later...
They make a product we call "bending ply" which is plywood with all the strands going the same way...it bends without having to steam it. It bends along the grain, so it is directional. It's available in 1/8" & 3/8"...we are planning on using the 1/8" and adding a birch veneer to re-construct our modified beds. (they were originally twins, changed to double by PO, now we're going back to twins).
It's available at larger commercial lumber yards. The one in Denver is
