Received the upgrade package the 1st week in FEB. I had already dirlled out most of the solid rivets while waiting for the upgrade. At the time of this entry, I have trimmed the rear ribs and installed the upgrade extrusion with solid rivets. In addition to the plans, I replaced 2 solid rivets with 1/4 inch AN Bolts on the extrusion. I purchased aircraft quailtiy parts from Spruce Aircraft. After bucking the rivets, I mearsured each one to ensure that the "shop end" was 1 & 1/2 times the diameter of the rivet shaft.
