You can either get Street Scene or M3 mirrors. Check them out
www.stylinconcepts.com or
www.godfathercustoms.com just to name a couple. They should have a list of mirrors that will fit your truck. I think the Street Scene mirrors conversion kit from manual to electric are better, just my .02.
To get the door panel off isn't that hard. Just need to remove the window crank, if its manual windows. Take out the screw behind the door handle and remove the plate. Use a door trim tool to "pop" the plastic tabs out of the door. Be careful not to scratch the paint behind it. once the bottom section is loose, pull up to free the door trim from the window area. Installation is just the revesal.
The dash bezel - remove the screws to the lower panel under the steering column. Or enough screws to push it down slightly. There are 2 screws that hold the bezel to the dash, you just need enough room to get a screw driver in there. Remove the one screw thats on the top of the bezel, straight above the clear plastic. If an auto, place the truck in 1st gear to get the shift lever out of the way. Tilt you steering wheel down and pull the bezel towards you. Watch out for the hazard switch that the bezel doesn't catch it, because they break easy and are expensive to replace. It's just clips holding the bezel to the dash. Once the clips release, pull it away enough to gain access to the Airbag shutoff switch and headlight switch and disconect them. Don't worry the airbag wont go off.
It shouldn't take but maybe 10 minutes each to get them off.
