Ruger Red Label Shotgun 20 gauge Ejector; Serial Prefix 401

I purchased the right side ejector from Numrich that stated that it was compatible for my serial number prefix of 401; the Numrich part number is 1803130.  However it does not fit my shotgun.

I called the service part number and they recommended that I return the 1803130 part and exchange it for part number 117-0430; however, the 117-0430 part says it's compatible with serial number prefixes 400 and 410 serial number prefix.

Do you know if the 117-0430  part will fit my shotgun with serial number prefix of 401?

 

Please return the incorrect ejector for #1170430. Thank you.
