I can't find a replacement for my 2012 coupe drivers side door actuator. The original part number is L22770939 but it was replaced with 22922931. The numbers come up at rockauto, gmpartsdirect, etc.. but all of them show it as being discontinued. I bought a similar actuator from Dorman (931-394) but the emergency release cable hook-ups are not the same. Everything else about the unit appears identical. Any help would be greatly appreciated.
