Hi all, looking for some advice on getting a steering box from Paddocks. They have 2 new Adwest units available, an outright buy for 280 + vat (cheaper than Adwest direct) or an exchange for 320 + vat with 100 + vat surcharge, which I assume is refunded if they accept my old box. I have a Disco 2 (4Axxxxxx)

So really I just want to get your experiences with exchange items from them, do they normally accept the old boxes or will I end up stuffed?
