HEATER channel for T25 - correct spelling (just noticed)

[acerimmer5]

hi and good evening - does anyone know if the heater channel for the t25 (the one that pushes hot air to the back seat passengers) will fit round an auto box - interested in buying one and just seen it on fleabay - however if anyone has one for sale that fits auto i would be interested - additionally the side panel on my van has rotted badly (where the fridge exhaust goes) probably due to the fridge installation and would like to replace the whole panel somehow - does anyone know where i can get a replacement - and finally the panel towards the back of the van situated after the sliding door has rotted round the window due to bad installation so a new panel is needed for that - any advice on how to fit these would also be appreciated - regards - john
