Box floor supports - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I put a wood floor box on a metal floor box frame and seem to be missing something in the middle for support.I checked my parts trucks but they are all coil and do have a support connected to the shocks(ie brace between frame between wheel tubs). This is a leaf spring 1/2 frame and I checked my parts trucks but none of them are wood floor and none have that support on the springs. There are no holes drilled in frame by the springs and I got it this way. What am I missing and what interchanges between leaf and coil and 1/2 and 3/4. The floor just doesn't seem supported in the middle right

Looking at my LMC catalog shows the rear cross sill, next are two equal length sills, a couple of center bed reinforcement strips and then three more sills like the equal two. You are missing some parts.
Bet you didn't want to hear that , huh.
