To swap the whole hatch I believe all you do is remove the hinge bolts and replace the hatch and install the hinge bolts, you most likely need 2 people to do this though as the hatches are quite heavy to try to maneuver around while trying to install or remove the bolts. Has anyone been able to install a rear wiper/washer on one of these hatches? My 84 B2 doesn't have one, even with the fixed rear window. Are there any writeups anywhere that explains how to do the swap and anything about installing a rear wiper/washer with the opening rear glass?
