When I was putting mine on, one of the ball studs on the hood snapped. I don't know if it was bad or I just overtighten it. I sent Redline an e-mail about it, they answered me the next day. They didn't ask whose fault it was, they just sent me new ones. It took about a week, but they took care of the problem. Good customer relations--I'm going to order a set for my daughter's Grand Am. I'm extremely pleased with the way they look.
PS. I waited until I had the parts before I installed the struts. I hope you didn't screw yours up or mess up the hood by putting on just one side.
