Where can I find a replacement LCD connector bridge-board?

Hi all!

I am helping out at a fellow electronic repair shop and picked up this repair half way though. It looks like who ever opened it before lost the little connector board that fits between the LCD flex cable and the motherboard. The gap created by its absence is too much to bridge with solder, and trying to find this little piece online has proven difficult to say the least. The device is still working in all areas; we were able to take another surface pro 3 apart that we happened to have in the shop (for another customer) and found what was causing the display issues.

Does anyone know where to find the small connector board that sits between the LCD flex and motherboard?

Any help or suggestions are appreciated.
