That is the current plan...I spent two hours today attempting to remove one of them with no luck. I had the exact press they used in the video, but it just mushroomed the bolt. The only option now would be to drill it out, which I am hesitant to do. In terms of prep, I'm confident it could still be done properly even with it on, the guy whose going to do it was optimistic it could be prepped properly. If it was as simple as drilling it out, I'd do it but I'm sure theres more to it than that. Correct me if I'm wrong
