I haven't replaced the door handle, but on the Formula that the club owns that's at my house, the driver side door didn't open via the (oustside) handle, so I replaced the wire that goes from the handle to the door mechanism in the door. Kind of tricky.
I also replaced the entire doors on my yellow car with other doors that had power windows and good glass in them, and had to mess with the handle linkage when putting the skins back on.
But I don't have enough memory of either operation to give any exact help.
