When you hear the term 'original reproduction', what that means is that the part is someone's *attempt* to reproduce the factory part. THere are many aspects to their 'attempt'... materials, processes, appearance, function, etc...
Some of these attempts are very poor, a few are 'pretty good', but NONE are 'perfect'... you should keep that in mind, and examine as many *original cars/parts* as possible before making your determination.
