Door Lock Problem

Looking for advice/a decent diagram of a door lock off a 1986 registered land rover 90, ex mod. i have managed to get the old one off and apart to drill the barrel out but havent the slightest how the bugger goes back together. any material on this matter would be greatly appreciated. all the best, Pete

hasnt it got one the other side you could take apart to see what the first one should look like ?
