shaving my drip rails, 73 dart

With the little chrome/weather seal in place. Pretty big damn gap.
I think im gonna end up making a sheet metal peace that i'll weld in the same place as the drip rails, feather it into the existing metal so it looks seamless. then I'll have this strip bent at the end, in the place at the chrome/weather strip piece, so that it will hold the weather stripping in...
