Has anyone used rsk fiberglass before? And specifically their one piece clip for the 2008 and newer chevy silverado 1500? The clip looks pretty nice in their picture but I am wondering what their fit and finish is compared to one of the larger companies like fiberwerx. Also has anyone used the trailer products chevy 1 piece clip? I have heard of a couple instances that trailer products clips did not fit, this was on fords though. I would stick with fiberwerx but they do not make a 1 piece clip for the 08 and newer chevys. thanks for any advice in advance.
