I do not know if you are going to find it. IIRC, 2013 was the first year that they started the exclusive download from the MS mother ship (no DVD in the retail version). I did a quick look at the vendors I use and one vendor had an Access 2007 but nothing for 2013. They had some Open licensing options, but I do not believe that is going to help.
As for Access 2016 on a system with Office 2013, I believe you may find some references to people that have done it. I have always considered it expedient to not mix the versions, especially after 2010.
