I just got a 09 Silverado and i cant stand the 2 upholders that are built into the armrest. They are huge and the little rubber pieces do a real poor job of keeping your drink from moving around, i've spilled my coffee all over numerous times already and its a real pain to have to keep one hand on my cup whenever i stop, turn, etc. Anyone else having this problem? Anyone know of anything i can do different? Anyone know of an insert that you can put in there so a normal cup/can will fit betteR?
