The tonneau and boot studs just forward of the trunk lid and aft of the opening have become loose over the years on my 65 BJ8. What is involved in tightening these up? I did a quick look under the trunk lid and the studs are not easily accessible through that route. I would like to tighten them up and thought that someone on the forum would have done it before and would have determined the best way to do it. Appreciate your help! Thanks again, Stever
