Here's the info that Mar- K sent me:
Here is the information for the bed mounting blocks on your 37 Chevy short stepside bed:
The order in which parts are installed on the truck frame is (from the frame up): rubber pad, wood mounting block, cross sill bracket/cross sill, and the bed assembly.
1. The pair of smaller blocks with the center hole go under the 1st cross sill (back from the cab), which is the first bed to frame location.
2. Make sure that the wood blocks with the offset hole are located under the third cross sill that has the offset hole cross sill brackets attached. This is the second bed to frame location.
3. At this time you need to install the large wood blocks at the rear of the bed. These large wood blocks fit up against the bottom of the edge boards and rest on the rubber pad on top of the frame. The notched cut on the bottom of the wood block should be against the bottom of the bed side. The rear most bed-to-frame bolt can now be installed. These bolts hold the bed-to-frame blocks in place.
Hope this helps. Let me know if you need anything else.
Thank you,
Vickie
