I tried over and over again to out my diffuser in but it just won't line up. Who should I call do come do it, can a mobile mechanic do it or do I have to have it towed to a body shop? One side the upper diffuser tab isn't sticking through the slot so I can't push it flush, the other side I have the tab sticking through but can't get the sides to pop in. This is waaaaaay harder than I thought, any suggestions?
