Can it be done? I think mine is leaking in my nt and have a good condition wt one sitting at home in my spares

And is there any good serviceable parts that should be changed before refitting?

Put some new foam on the top and bottom flaps. Also a good time to pull the heater core out and clean all the seeds/leaves out.

95% the 1.0 box isn't going to fit into the 1.3. They are fundamentally different from a control point of view, (so the dash levers aren't compatible) and the vent hose arrangement is different, and they are a different shape.

I'm going to say it's not possible. It might physically fit, but I don't think you'll get it working.


The heater core might be the same, so maybe you could swap that over?

I've had both styles apart before, so I'm speaking from some experience., though I've not tried to interchange the boxes.
