This is a picture of the rust cut out.

RE the fuel tank, though the race car and the racing results are awesome. Is that a sump on the bottom? I was always afraid to let the fuel tank get too low in the 77 coach because when all the fuel runs to one side going around curves the engine would temporarily try to run on air which diminished the power a tad. A sump would be a great solution.

Yes, it is a large sump with a drain petcock on the bottom.
On my 1981 newell I ran out of fuel when the tank was low on a steep incline.
I usually try and keep it above 1/2 tank and on long trips 1/4 tank
