They are good thank you although I had to read it a few times to get it completely. Figure 2 shows just 2 sills so I presume those are the last two at the rear of the bed. The front one would mount the same way but with the longest bolts.
On my 49 I am missing the pads under the wood blocks at the next to last sill at the rear. The blocks I have in that spot are 2.25 inches.
Question are all your blocks 2.25 inches which would mean I need a pad under mine.
