That's why I asked if you wanted to keep the heat and/or defrost. You can do it, but you will have to make sure the air flow is routed properly without the evaporator box. If you don't want them, it wouldn't be a whole lot more work to remove the stuff under the dash. If you aren't going to use it, I would guess you are racing the car. And the easiest way to remove 100 lbs. from a car is to find 1600 places to remove an ounce. Get the weight out of it.malc said:Wait a minute.
Could I cut that box off at the firewall and remove the aircon stuff in it,
leaving all the stuff inside the car intact ?
