GM Flatbed?

[Jimbo0076]

My 66 GMC C30 has a flatbed that looks like it was put on the truck very shortly after it was new or when it was brand new and is made all out of wood except for two small bands around the outside of the bed. Now its getting rotten in places and I'd really like to replace it but still have a useable truck but keep the old look. I seen pictures of the rounded corner flatbeds that seems to of been a dealer option for these trucks. If so does anyone know where I could find the outside rounded rails or aftermarket ones? My bed is 12' long but could possibly be shortened to 10' if need be. I can build one out of angle iron and such with no problems with a wood floor but really like the look of the older rounded corner beds.
