For the reasons mentioned in the right fuel tank entries, I had to replace the rear baffle. This went just fine. The hardest part was making sure I maintained allignment between the ribs and skin while match-drilling the baffle from the inside-out.
I had yet to drill the skin to the baffle, so I I took care of this while I had everything apart. I also marked the filler cap location (and drilled a pilot). I marked and drilled the hole for the drain flange and then drilled the flange to the skin.
