I will never understand why we can not duplicate parts that were made 40-50 years ago. The first question manufacturers need to ask themselves is "does it look just like the original?" If the answer is NO then they need to go back and try again.

I'm glad I can go buy a new air filter but for a buck and a half I want it to look like I just spent a thousand on a NOS one.

So now everyone will see the difference and say "my so and so isn't that bad" and not buy one. Then because the manufacturer F'ed it up sales will be poor and they will say its not worth doing in the future and everybody looses.
