As we had previously posted, we had a new piece of a aluminum cut at Discount Steel and we received delivery today. Those with a discerning eye will identify that the piece is like a U-shape that encompasses the rear window.  This isn't exactly like the original.  When Jim did the shell-off restoration of the frame and the flooring, the new flooring ended up being a tad bit wider than the original.  Because of that, the rear of the shell didn't fit exactly back together where it was originally riveted.  Now, most would say, "Hey, that's not good", well, in this case it's actually okay with me.  I like the idea of this new aluminum, which I purchased at a slightly thicker grade than original (.040 vs. .032) will support the window better.  Also, the rivet holes that were drilled in the rear are a little too big for my comfort in the original pieces so this new piece will cover them over.  All in a good day's work!
