Caravelle heater duct to rear

[Quzzy]

RESOLVED it was hooked under the front ducts and a lip at the rear bulkhead. Hi, I need to remove the Caravelle heater duct that passes between the seats (gearlever service and carpet fitting). I have loosened the two obvious vertical screws towards the front but it seems firmly fixed still. Can anyone point me to other clips /screws? Thanks.

At the rear there should be fixings near the outlet.

Thanks, found a diagram that showed 4 screws there but in fact it was just hooked under the bulkhead lip and no screw holes. It would be a real pig to get it out as all my solar control gear is there and leisure battery etc. So going to cut the rear 300mm off, which will allow me the drop the battery 40mm and make it easily removeable to run cables/fit carpet.

It’s hooked behind/ under the lower dash cowl and there’s 4 possibly 5 screws at the back
