Over the past week or so I've been busy with non-RV stuff. But on last Friday, the replacement F-684R showed up from Vans. Learning from prior mistakes, it only took about 1/2 hour to get it knocked out, match drilled and clecoed. Edge distance all good!
Moving on, I fabricated the F-769L and associated shims, but when I match drilled it, I just wasn't happy with the fit, so today, I took another crack at it. It's physically impossible to get good ED on the 3/16 holed that are common to the exterior steel fuel tank bracket, due to the way the F-969 aft edge butts against the F-902, but by clamping the heck out of this to keep it all tight, I was able to get 5/32 ED on the F-969L This is the same as the other side and it as good as it's going to get.
At this point, I'm happy to say that this step is complete.
