retaining

On two of my seatbelts, the small black plastic studs (about the size of a 5p coin) that prevent the chrome fixing buckle from falling to the bottom of the belt have broken off and gone missing. Its only a small point, but its annoying. Are these available to buy and fit at home? :confused...

Hi all, wonder if you can help. I am selling my car with personal plate which I am going to keep. The buyer wants to buy my car and put his personal plate straight on, can we do this? I don't want to keep him waiting for the dvla to first put the original plate on the car, (when I bought it)...
