the belt line on my cab appears to taper.unfortunatly as i'm typing this i realized ,no.i havent measured it.duhh.but its obvious that it does.drivers side lines up with door nice.but no way the passenger side is gonna line up.has anybody ran into this.i mean its not the end of the world.i'm not going to wig out or nothin.but its probly off by 1/8"- 3/16" or so.we really worked to get it this close.just curious...............dave
