Classic ind is selling the same parts that all other resellers sell.
Some of them yes, some of them no. Consider turn signal switches: the vast majority of them on the market right now are Chinese junk, but they're not all the same. Some of them are even crummier than others.
Some of that is more than one "company" in China making a given part — it's more common than you might think — and "company" is in sneer-quotes like that because it's often some individual schmoe in the rough equivalent of a dirt-floor shack.
Some of those schmoes are very good at making things that
look a lot like the sample (for a
little while, maybe long enough for the end user's payment to clear), out of materials that
look like the specified ones.
And some of it is just the way stuff works in China: dozens of outfits market a given thing and claim it's their own work, but it's just a pecking order of who paid how much to include it in their product line. Those who paid more (and/or their brother-in-law is the schmoe, or they have other connections) get the least-crummy parts. Those who paid less (and/or don't have connections) get the most-crummy parts.
Then along comes the Westerner, with his cute assumptions about adherence to specifications and quality control, etc. As far as he's concerned, just lookit, it's capitalism! Otherwise why would he be able to shop on price? And then he goes bіtching and moaning when
this inevitably happens.
Same planet, different worlds.
That's the kind of thing one gets to learn as a product development manager. Also see
here.
If it wasn't for big resellers like Classis and Year one there would be far fewer aftermarket parts available.
You think Classic Industries and Year One are driving the likes of Standard Motor Products to keep those locks in their product lines? No, sir.
