the top one has five bolts - two in the door and three in the pillar. The bottom has five bolts and two rivets in the door. Make sure you disconnect the check strap first if your going to remove the door.
FFS m8, Rivets are rivets .... have you ever considered getting up off your arse and going to have a look oris it too feckin easy to get someone else to do it for you?
Go out, have a look at it. If you cant find the rivets, take the Disco to a main dealer.
Thanks for the chearfull responce, I struggled to shut the door when it broke so I don't want to open it just to have a look to find I cant shut the door again becuse I have broken the other one too, then I will be left with a rear end convertable.
