OK here is the latest, took out the glove box, yes six screws, NO laying on your back, Broke filter into thirds and slid it back in. The wires are not a poblem when the glove box is out.
A little trick when you go to put the box back in take some "C" clips or use small wire and wrap around the top screws at the base, the ones thru the vents. keeps them from falling out, Also much easier the put the passenger heater tube back in place.
SO much easier at least for me as could see everything. I can't see up close any more and by being on your back under the dash things were not far enough away.
