I need some advice on removing the dash. I have removed all screws from top of dash, steering column, and glove box. I was able to remove the steering wheel with a three arm puller. Now that I think I have everything ready I'm unable to remove. It feels like it's attached with the two end brackets on each end under the dash. Now that I have arrived at this point I'm concerned about how difficult it will be to put this back on and align. The reason for all this work is to install a heater that has all the duct work and vents. I am rethinking this purchase and wonder if a less complicated system would have been just as good.
