Welcome and best of luck with repair. As said above by scoobysub, there is ALWAYS more to it that seems at first. I just put 120 hrs into a Capri that was in for inner and outer sills drivers side , outer sills passenger side, bare metal strip down , repairs here and there and a "new " wing that didn't fit at all. Had to cut out front portion and back portion and stitch them onto original wing. Another fella has probably about 40/ 50 hours in it too. It's not in primer yet. Kept finding more rust as car was being sanded...
Hopefully you don't have that happen.
Best of luck with the pr
