steve, take out your radio console,remove the screws from the heater core-blower unit, line up hose, replace screws, pop hose over plastic defrost vent tubes on both sides, replace console,. no problem.
That's not a bad price. There really is not too much to it. If I remember right there is a rubber boot that fits on the heater(kind of Y shaped) and the two hoses that go to the defroster vents. Should work fine for you. You are quite the Ebayer these days.
