i don't know of any diagrams on the Internet but i can explain to you how to do it,first you have to remove the door panel from it then you will see the pop rivets that hod the regulator assembly in the door,you then have to drill those out to get the door glass and the window regulator assembly out,it may take two people on this one though because someone needs to guide the glass out while someone is holding the regulator assembly,once the glass is out you can then remove the regulator assembly by guiding it out though the opening on the door,this is a little difficult to do so take your time with it,when your installing the new one you can either pop rivet it back in or use bolts on it either one will work,just make sure the bolts aren't too long or they will cause it to jam up or get hung,if you get someone to help you with it ,this will be a much easier job to do,all you have to do is take your time with it,there's really no way anyone can mess up on doing this other than not getting the regulator assembly back in tight enough,just be careful of what your doing on it and nothing should break or tear up,good luck with it.
