Welcome to the FORDBARN ! I to have a 39 truck. There is a gentleman in Vermont that is in the process of making beutiful center grill trim strips for the 39 truck . As you have figured out ,this is a very tough part to find in ANY condition. I recently held one of these reproductions in my hands and was VERY IMPRESSED ! They are very very nice ! ! The surround piece is another matter . it took me 6 years to find one of those for my truck they are not being re-produced either . The center trim is a one year only part ,as is the 1938 truck . the surround trim is the same on both ..somtimes you have to buy the whole grill ,just to get that one part,,,and then send it out to a pro ,to be fixed up/straightend. As these trucks gain in popularity you might see the big boys start to re-do some of these parts ,but I woudn,t hold my breath. As far as the bed goes I,m not sure on that and will leave that to sombody more knowledgible on the subject good luck MP
