Hi, I just found lying next to my Sonoma a rubber donut marked 14032743, which is a rubber cushion that goes under the radiator support. I haven't had a chance to look under the truck because we have a lot of snow on the ground, but I'm assuming that the nut under this came loose, or the bolt rusted through. Can someone tell me how hard it's going to be to replace this, and if I need to remove other parts to get at it or if I can just slip everything in? Also, I see that Dorman sells a kit that seems to consist of all the parts that go with this, anyone have any experience with that? Thanks!
