Hey friends. I just bought a third row for my yukon. When I started to install the bolts I ran into a HUGE rust issue with the nutserts or weldnuts whichever you want to call them. After about 2 hours of wd40 and starting the bolt and backing off then going a little further then backing off I was able to get 1 bolt in and only 13 more to go. I believe it was shear luck that I didn't break it. Not wanting to test my luck any further, you guys have any tips that'll help me??
