Larry Like you I did not like the back rest belt area, so I used 10mm A/C ply for the shelf, on two 3/4"spruce cross members, then on the double longerons, where the 10mm ply is glued with T88. I put a 10mm ply webbing under those longerons which tied them all together I then placed 5/8"spruce from the rear spar to the parcel shelf, near the centre, and then two more from the rear centre of the shelf to the bottom, longerons, Why, because I will be using the shelf to sit on or lean on when getting in or out on the KR. And when I get the belts. I will use aluminium plate on either side of the self, or even glue another square of 10mm under the shelf for some extra thickness for the belt bolts.( or both). only to make me happy.
