Reproductions are designed to fill a market void. And this is just MY opinion .
But in my mind there will be - has to be something to differentiate the originals from reproductions. ( keep sellers honest imo)
2nd - With any reproduction there will be concessions made in regards to some of the smaller details. Think of the costs involved to either tool up for every single piece, or use currently avail smaller pieces. Lets be honest how many here would pay twice( maybe more, maybe less) the price to get an exact duplicate of an original set?

I'm happy with a nice set that looks the part within 90%. Personally,my cars are not garage art/trailer queens. Mine will be driven. So I'm not one of the crowd that needs $400 nos plug wires
