I built the bed on the truck a little different than Brad. I first put two 4x4"s across the frame and then put the sides and front panel together and installed the bolts finger tight. Next I installed the rear sill and the cross members. After that I put in the two outside planks(with the mounting holes) with the bed strips. Then I was able to aline the bed with the mounting holes and remove the 4x 4"s and lower it into place on to the mounting blocks. Next I installed the rest of the planks and bed strips finger tight and squared up the bed, then started tightening All the bolts in 3 stages.
