I took a look at OP’s machine and it appears to be one of those deals with one big central hinge cover with upper and lower clamshell halves. So, we’re both sunk. It’s symmetrical in this case, but there is nothing to mirror. They will need to have an existing one (or all the bits and pieces of their busted one, maybe) to measure up and clone.

But yes, I have also seen laptops where the left and right hinges and/or their covers are different from each other.
