Wow, I'm impressed with that roof replacement. Question, did the J bolt bracket come with your replacement trunk or did you find one separate? I used the two piece trunk floor and it did not come with one.
You know, I don't have a good answer to that question. I bought the complete trunk pan to replace mine, and I suspect it did not come with the bracket much like it did not come with the tank strap mounts that are welded underneath. I think the bracket was repurposed from the old trunk floor that came out of the car. I actually have another spare tire well out in my garage with the bracket still mounted in it. I would be happy to cut it out and send it too you if you need it.
