Stop in for a cup of coffee

so.. made my window stud washers out of leather.. so that's done.. waiting for some rubber dip to show up to cover the upper stops so they don't hit metal on metal.

My drivers door, when i close it the rod that goes from the handle to open the door, back to the latch sort of vibrates/rattles and i can't have that.. any tips? Was thinking of cutting a piece of hose lengthwise and putting it over the rod with some zip ties..
