My 70 cuda's trunk well is completely rotted out. huge holes. I think this car was parked early in its life outside with a leaky lid and a puddle of water in the well(it's been stored for 14 years) because only the well is rusted through. There's plenty of paint and a some surface rust elsewhere in the trunk. The extensions look excellent from the tops and backsides after poking and prodding (Behind the rear quarters).

So given that I am ordering a one piece trunk floor, would you just cut out the well and replace it, or would you take everything, all the way to the wheel wells and extensions? Which would be easier/make more sense?
