I'm kinda surprised at some of the reactions here. Everybody was telling the kid with the Swiss cheese cuda to go for it. You've got a bum lid and everybody's telling you to bail. Scamps are rare and cool, fix it.
Put up a wanted add on here for the Dutchman panel. You'll have one pretty quick and it's easily shippable. You don't need quarters to get the sail panel legs. There's cars getting parted out on here every day and most have rotted lower quarters. Somebody will gladly cut out the upper section for you and it too will ship easily. The roof skin will take a little longer to find locally. They're around though.
A used welder and a spot weld cutter and you're in business. You can learn quick enough to do that. It's not like welding bridge supports. It's only tack welding.
