Looking for Rear Driver Side Door Lock Actuator

[carbuff74]

Hi Group,
Just purchased (yes I know its not a 300M) - a 1997 LHS.
I am trying to get a door lock actuator for REAR driver's side. Plenty of aftermarket (dorman) replacements for the front doors. But cant find anything for rear. Not sure if anybody is parting out or has one to sell. Thought I would ask here before going on a goose chase in the salvage yards.
Thanks.

4574023AE appears to be the latest P/N however discontinued virtually everywhere.
Someone may have one, not sure.
I do not but there are at least M's in a local yard.
Part would be around $40 plus shipping.
As long as Ian doesn't wipe us out I may be able to get one early next week.
