RHD Drivers Seat Runner (S2 Exige / 111R)

I’m looking for a seat runner, RHD drivers side, to fit a seat from a 2010 Exige.

Think the Lotus Part Number is A120B0155S

The seat part number is C120U0045J and it definitely needs a different runner from the one I have in my 1999 S1 Elise.

I’m happy to collect from anywhere in SE England.
