Default motor mount differences

I have two motor mounts here.
one is for a Z06 & ZR1(part#25966517)
and the other is for base and GS(part#15254700)
Here are pics side by side.
What the heck is the difference?
They look identical. Is there an internal difference? The price is different!
(The one on the bottom is the ZR1)

The rubber has different numbers molded into them. There must be an internal difference

Doesn't mean they're different....just marketable...

Which one of them is made in Korea? Or are they both made there?
Maybe that’s the difference? Or maybe the Z cars have a higher durometer rubber or a heavier viscosity fluid in them??

They both weigh the same as I can see, but I don't have a scale that will go down to ounces. Yep, both made in Korea. A builder told me the steel plates are thicker. Hmm, not sure if I believe that. He said they cut them open when bad and there is a difference.
