Still at it. (Again, I am working with the major components I received when I purchased what I thought was a 1940 KC 1/2 ton.)
I am in the process of mounting the '37-'39 bed on the frame which appears to be a 1947. (So far, I have been able to do this with no permanent modification to the original parts I am using.)
The front cross sill bolts go through their blocks and through frame holes which were already in place. The third cross sill required me to create plates for the mounting blocks to rest on as the frame is wider in that area than the bed was designed for.
I am now looking at the rear mounting blocks for the bed. I would like to see a photo of someone's 1947 so I can be assured that I am not putting the bed mounting blocks in where they will interfere with bumper mounting hardware.
To be honest, I don't know if wooden blocks are even used at the rear of the bed on a stock 1947. I will have to use some blocks toward the rear to secure that part of the bed I am using.
So, if you could post a photo of the corner of the bed on a 1947, I would appreciate it.
Thanks!
