Cab bed repair - Part 5

I mentioned in an earlier post that the new side walls would have to compensate for the difference in the new bed frame vs the old.  Here's a side by side photo of the old aluminum and the new wood
frame.

The original wall height below the window was 9 1/2 inches while the new height would be 8 7/8 inches.  Here's a photo of my sketch to determine dimensions and how I would place the screws.

I had to remove additional damaged plywood under the window and rebuilt the wall using the dimensions listed above.
