Yes, that's exactly the sort of thing countries at laptop.org should be
able to answer, once you give them the SKUs you have.

While you might only need one part, the base upper assemblies are
constructed from multiple parts, and when they are swapped in there is
an inevitable waste.

The mechanical, electrical, and communication protocol compatibility
is maintained at the interface between the base upper assembly and the
rest of the laptop.

The parts themselves are not backward compatible within the assembly;
you can't take one of the parts off an assembly and expect it to work
or fit in another assembly.  It might, but it isn't _designed_ to.

This is why a source of second-hand parts may not meet your needs,
especially if they have been broken down into smaller parts.

Upper Assembly""

touchpad+keyboard come together as 1-unit, called the Base Upper
