The bolts fit from the outside .ideally a two person job but managed on my own.
Line up carefully and mark the holes ...then check again.
Use a punch to mark a drill hole ,small drill then larger to get a good tight fit..
Same for the window / door bolts but the bolts will need tobe cut. I used steel washers on the inside between the nut .also I ran a bead of silicon on the rear and around the holes just to be sure.
Two hours work job done..make sure door joints are as tight as you can get them.

Hi Terry,
Thanks very much for this - very interesting.
I'm wondering whether to get some aluminium rivet nuts and use them instead of the self-locking nuts provided. That way I can do the job alone and also avoid an electrolytic corrosion between steel bolts and the body of the car, if any moisture gets in.
The only downside I can see of doing it this way is that the bars will stand ever so slightly proud of the body of the car due to the head of the rivnut. But sealing along the upper side of the body bar with silicone should prevent any water running down, and the metal bar is plastic coated or something anyway.
You had to cut the bolts for the door? I would have though the gap between the door and the door card is sufficiently deep. But then again, you've done it and I havent!
Am also thinking of getting some plastic grommets to seal up the holes in the bars to stop moisture getting in (and thieves undoing the bolts).
