I have issue with cars like that. There's only so much bumping and welding that can be done before you have to start cutting and replacing. For a resto mod or non-numbers car it really doesn't matter just make it nice. But for a high dollar numbers matching restoration, well it's only original once, and the more that is replaced, the less of the original numbers matching car is left.
I've seen rare cars reduced down to nothing but cowl sections with VIN tag for sale before. I'm sure people have waded through the murky water and "rebuilt" those rare cars. I stumbled across this '64 Impala convertible cowl with a/c for sale on ebay ($2,600) the other week. I'm sure someone will "rebuild" it since the price on these cars has gone stupid. Maybe one day in some years to come this "convertible Impala" will be for sale. I just hope the potential buyer knows.
