my integra is currently grounded for a few days, i had gotten a flat tire and as i went to take off my wheel to put on my doughnut i realized that a lugnut had magically disapeared, when i took off my wheel i had noticed that the lug, where the lugnut screws onto had actually broken off about an inch and a half down...can i just buy another "lug" or do i have to buy the whole hub? i can get one at a junkyard probably, how hard are these to take off? thanks in advance
