Dart dash removal

You can leave the windshield in but you'll have to cut bottoms of the "J" nuts off from under the dash and push whats left of the bolts up through the hole and fish them out from under the windshield gasket. To re install the dash you put new "J" nuts on the dash instead of the body and bolt or screw the dash in from underneath. It's harder to pull the dash with the windshield in but it beats having to pull the glass and risk breaking it if you don't have to.
