Get em mounted somewhere then bolt them on yourself or watch them properly torque your lug nuts on. If they use the impact wrench they will strip your lugs.
I just had a wrench thrown in my trip to Cali, my tranny finally gave out.... just one thing after another for me. Wasn't driving it hard and didn't hear anything break but 1st gear makes a loud clicking/rattling noise, second gear is fine. Anyone know what a broken tooth in a 5 speed sounds like? Guess its time for a 6spd swap :-/
