The eyebolts on my 07 ML350 are stained with rust. I thought about getting some aftermarket screws but decided to give these a try. Looks great. I've noticed a few reviews saying these caps are tight and parted. All you have to do is spray the eyebolts with a lube like Balistol or WD40 before pressing the caps. Easy installation without disconnection. The residual lubrication also makes it easy to remove if necessary.
