I'm looking very closely at it. The ribbons are in the right position for the JX as far as I'm aware.
And yeah, as I said, you won't get the keyboard alone.. you'll have to get the entire plate, which includes the keyboard, mouse and power button.
P.S. It's an absolute B!TCH to connect the keyboard ribbon.. be VERY sure you've got it slotted in square on before you latch it (seat) after attaching the lights and touchpad.
