Another vote for 97+ ones.
if you have electric adjustable mirrors on your 96-down it is fairly simple to set the 97+ ones up to work with the controls, just a few wire splices. The heated mirrors are a bit more in depth, you have to run at least one new wire to each door and tap them into the rear window defrost wiring. I can't guarantee this is accurate, but I believe the black wire with a red stripe at the defrost switch is the one you want. Check your wiring diagrams (FSM preferred over Haynes/Chilton) and decide if you agree before wiring it.
