So recently I've discovered my trunk floor is rusted through in quite a few spots. I don't want to let this continue, so I plan on fixing it up this winter while I have the car parked. Ideally, I'd like to just cut the whole floor out and weld in a new one, but I am unsure of a couple things: a) Is there anywhere I can buy the trunk pan, like how you can find floor pans for the older cars by chance? b) Does the trunk floor have any structural significance to the body or chassis of the car? I ask the second question because if the answer to "a" is "no", I'd consider riveting in sheet aluminum or something similar to a) save weight (not that I think itd make that big of a difference, but why not?) and b) have one less place to worry about rust. I also ask so I know how careful I need to be while cutting the floor out. I'll be dropping the gas tank to get it out of the way as well, obviously. But is there anything else I would need to know before setting out to do this?
