Help on a part number please

Need help on a part number. I need a new light bulb receptacle for a Magic Chef Mod # 6898VVV Ser # 28903014QV.
When looking up the part I see 2 to choose from depending on whether oven is a Series 10 or Series 30. I don’t know thus I’m not sure which receptacle to use in the oven.
2 Choices for part are 1. #AP4101776 (Manuf # 7407P088-60) or 2. AP4093142 (Manuf#74003125).

Also, can I change this from the inside or will I have to remove the back cover?

Any help is appreciated.

Thank you

Jeff
