When we rebuilt our 66 Safari, we were fortunate enough to have had an acquaintance with Mimi who had our exact model and package, but original. So we rebuilt back to original with her giving us dimensions. I like the way the sliding shelves have worked. As far as the curved pieces of wood, the only thing I can think of is a fire extinguisher mount. If you need pictures or dimensions, PM me and I’ll send them to you. Good luck
