Again, no pics...my bad. I got preoccupied with an issue...see below...
-Riveted nutplates to the parts that required them prior to assembly
-Riveted the aft left bulkhead to the aft center section spar, leaving the appropriate holes open for the vertical bar.
-Since I didn't take pics, I'll try to describe. The vertical bar is a beatiful anodized chunk of aluminum with 2 simple bolt holes and 2 rivet holes. I'll try to add a pic later. Anyway, the bar would not fit and have all the holes lined up. I was quite perplexed and wasted alot time trying to figure out what the heck to do. See next post for continuation....
