When my car was restored 14 years ago, I faced a dilemma; I had a "junkyard hood" that didn't fit properly. The restorer, a pretty accomplished body man, said he could work with the old hood, but by the time all is said and done it is likely that the cost might exceed that of a new one. I had the additional issue of the hood partially stripped to bare metal and sadly, rough sanded--something you don't want to do with aluminum. The amount of work required on that junkyard hood was look excessive.
The new hood was a known entity, a set procedure for making it fit and no mysteries. I chose this option. At that time, the new hood (sourced from MB at $1,700) was readily available and I don't think there were reproductions.
I'm well aware that money is often a deciding factor but sometimes in order to save a dollar, you end up spending $5.
With other threads talking about the high and higher values of these cars, think carefully about how you approach a major body repair.
