dart rear seat swap need help

The mounting and other things usually go by year blocks like, 67-9,70-2,73-6 and you just have to mod them to work for your year. The heater core issue,there are clips that go all around the outside of it so the inner cover comes off,then there are 4 screws that hold it in the other 1/2, you may have to take the 2 lower dash corner bolts out to make room to pull the cover off.
