I don't like that option!
1) you can't drill off the heads. The rivnut and bilt both spin. Then I would have to order new rivnuts and bolts. I noticed the bolt have some kind of nylon or something one then to keep them from working loose. Even If I could drill them out, I wouls have to get out the peices.
2) To get out the peices I would have to get at them from the inside of the vehicle. Like, would I have to remove the hedliner. If so I could probabaly hold the rivnuts from inside while removing the bolts. Is this possibale?
Damn, I was so happy with my self install.
I thought I did a nice job and saved some money!!!
PS: Does anyone know the easiest way to remove the headliner? I have a sunroof.
