Which picture are you refering to, Dave? I searched through my home computer and my Photobucket site for pics of my bed area. This is all I came up with. This was just after I removed the bed pieces and all of the rotten wood and etc. Shortly after this I hauled it into the shop to lift off the cab for frame prep and painting.
I know I took some other photos of the cross members before I cut the bolts and removed them from the frame, but they must be in my computor at work. I was kind of supprised too, that the bed sides and front panel just sit on the wood, which is bolted to the cross members. And the large bolts that attach it to the frame only go through 3 of the 4 cross members.
I have found out, through some communication with Mar-K, that they now have reproduction front bed panels for the 48-52 trucks. They've had the front panel for 53 and up trucks for some time, but they just came out with the one for 48-52. I haven't ordered one yet, because my project has been put on temporary hold through the summer. Once spring hit, it was motorcycle season and my truck work time ended. This is all the farther I am now, plus some body work on the cab, fenders, grill, etc, which is almost ready for primer.
