      This heater core is about one half thinner than the original equipment heater core. In order to make it fit, you will need to fabricate spacers to go around all four sides of the heater core so that the two retainer brackets will fit properly and secure the heater core in place and to prevent cold air from going around the heater core. If they are not going to manufacture the heater core to fit properly then they should provide an adapter to make it fit properly. I seriously question if the heater core will be able to to heat the air as well as an OEM heater core since it is only about 75% as thick as an OEM heater core.

      Bottom Line not recommended
