Well, thanks to Graeme the Dormobile is more or less complete again... I have an original wardrobe sitting in the back, requires some work but it looks fab in position (need to refix the mirror as it fell off..lol). Due to some corrosion on the fixed panel to the left of the door, there is scope for modification, which I am now considering!
In addition, the elusive missing dormatic front drivers seat is replaced! This seems to be of similar vintage but requires re-covering. I bit the bullet today and took the vehicle around to the car upholsterers around the corner (support local) and she confirmed that they all need to be recovered (I was born in Yorkshire, I had to ask

). I was hoping they could maybe re-use some of the original trim, but they confirmed that it wouldn't survive the re-padding experience. So, I am awaiting a quote and she is off looking for a decent substitute (square of fabric liberated from new seat), fingers crossed!
I have secured 4 x NOS door seals, so that is a start, still need to find some other replacement bits and now the reverse lights are working again

Can someone tell me how on earth you stop the wardrobe seat/step from swinging around when you are drivin (it is only temporarily fixed)?
Have attached rubbish picture....
