Hi i have 2008 macbook unibody and I recently replaced F2 and F3 keys no problem but when I went to replace the F1 key (that was only working when pressed with a pen) I realized the replacement key did not come with the small rubber bumper that is a contact/buffer between the plastic key and the keyboard. The stores that I checked provide the key and hinge. Do you have any quick fixes or ideas on where to get this part? See picture. It is a rubber buffer between the two circles i have drawn on the pic.
