shaving my drip rails, 73 dart

Update. Been at a stand still lately, money and other things going on.
Friday I am supposed to be picking up some sheet metal from a shop in town, they are also going to be cutting me enough strips bent into a "L" for me to use.
I ordered it 3"x1/4", this will fill the gap of the weather stripping, then I am gonna take the 3" and tie it directly into the roof skin. I will also end up supporting the gap under the weatherstripping with some barstock.
Hard to describe, hopefully will have pics up soon.
