72 Duster Street / Strip Build

Found a set rear rail cutouts I will be replacing these with. Little more clean up and spot weld removal to get the areas ready for the new rails... My poor air compressor is taking a beating on this job and I haven't even started sanding the shell down. Plan is to sleeve the new rail sections into the old ones by 3" or so on either side of the cut. Drill maybe 5 holes in the 3" sides and a couple in the bottom, plug weld the plates and weld the butt joint in the rails then grind everything down and POR 15 the entire underside of the trunk.
