Dont know about your year but on my 01 the upper or overhead handle the mounting points were there under the headliner. Just pulled the headliner down a bit measured and cut through the headliner with a razor blade to expose the mounting holes and within 15 minutes had an overhead handle. I do not think there was a provision for that on the a-pillar on my 01 on the driver side but pulling the a-pillar cover off will quickly determine that for sure. Pass side there was one on the a-pillar but no overhead one. Again though there were mounting holes under the headliner on the pass side and I added one there for my wife. If I recall the handles were 20ish from the dealer and included the mounting screws.
One note if you are tall and or lean towards the door on the driver side your head may hit it. I have on occassion and am only 6' tall. It is not usually a problem but again on occassion.
