Ok i am doing a unique radio install where when the glovebox is opened,you will see the radio at the back of it,but the radio will be mounted to a steel plate under the dash. in order to do this,the ac box has to go. it's no good anyway. the problem is, the heater box is in the middle of the dash,and the blower is on the other side. so heres my solution in mockup at the moment. this is the plate that attached to the huge hole in the side of the heater box, the round silicone ducting,will run up behind the radio and attach to the blower. the only reason the hole is so big,is they wanted to slow the air velocity down,so the ac core could cool the air, without it,all you need is a 3 inch hose, the air flowing into the heater plenum will slow plenty to absorb heat from it all you are doing is moving pressurized air from the blower housing to the heater plenum. it doesn't matter where it enters,as long as it's sealed. the black on the corners, it's there to make sure i marked the plate in exactly the right place. I happened to have a roll of the same foam stuff that was used to put together the factory system. I have everything in this garage. it's the same black high density moldable foam crap. i will run it all along the plate edges to seal it to the heater box. tomorrow the tube gets tig welded on,and the hole in the middle of it gets drilled. I was out there at the plant at eight tonight sawing and sanding the edges with a flashlight,the breakers for the lights were off.
