Perhaps check the pad sizes first, if they are larger than original, it would not take much to reduce a 2" Space. (the pads in mine measure 2" across the top edge and 1-3/4" across the bottom.)
I have never had a problem driving. If you need to remove the lever to heat it to bend it, which seems to me to be a last resort, you'll need to get under the dash. I have found the best way to access under the dash is to completely remove the drivers seat and plastic bucket. The steel frame can remain, just get a piece of heavy cardboard to lay over the frame. Then you can actually sit in
it and rotate so your feet rest inside the back hatch area, with your back resting on the cardboard, you can be very low and easily get under the dash to work. I know it sounds crazy but the seat removal only takes about 5 minutes.
Look for something simple first, good luck
