Hello mate, the bulkhead in good nick, needing no welding 'may' fetch £50-£75, the bonnets wortch a fiver if it's straight, the truck cab if it's in good straight condition is worth between £50 and £80, if it's got a headling and panels then you could be looking at £150 top end, the doors are worth aroung £50 if they are really straight with no corrosion if the frames are slightly crusty knock a tenner off. The chassis with a tax exemt log book that could be rebuilt could fetch £150-£200, the seats if they are good could fetch around £50, maybe £75 if they are the delux version, the axles aren't really worth anything, maybe a tenner to someone that needs one, I've struggled to sell a rebuilt 2.25 petrol with unleaded head, in the end it was donated to a friend who was short of cash, the gearboxs aren't worth much, maybe a little if tit's from a 2.
That's about it really.
