In the end, looks really good. Nothing like a few trials and tribulations to get there. Nice job on the access cutouts as well. I have to believe having that little extra storage space is pretty valuable. And great tip on the filler neck mod, I don't think I have seen that before so good to know.

Curious if you used the circle cutter with a handheld drill? I had a pretty bad experience several years ago with one of those (1/2" drive so a bit bigger) and after dusting myself off, looked at the packaging and it indicated "for stationary drill press only". I guess that was one of those "wisdom" moments.
