Inside Door handle Rivet

[Ohgami]

I was looking for info on replacing the Rivet to the Door Handle. I reciently got a New Door and My Interior is Gray, The new door handle is Tan. So I want to put my Gray Handle back on. I have seen Replacements for sale but they don't include the rivet either. Any Idea On where to get one or what type/size it is. I tried the Dealership even and they had nothing.
