So are you saying that those parts numbers are for c-max and kuga? The finis number I got from ford dealer and that supposed to be for focus. My reg is RA 05 GWU. it is 1.6 tdci lx estate. I need to buy a front electric window regulator driver side. Arevthose numbers any good to me? Looking at ebay all front electric window regulators for focus 2005 come out with this number 4M51-AO45H16-A

Any chance you could help me to solve this mystery...?

Thank you
