Are the outersills welded to the inner sill plates along the top and bottom edges? or are they welded just on the top edge and the finisher strip holds them in alignment with the fenders? I am replacing all these parts as mine were gone when I got the car. /ubbthreads/images/graemlins/canpatriot.GIF /ubbthreads/images/graemlins/canpatriot.GIF
