Hi Suzy I would imagine you have 22.5" wheels which is a standard lorry size so you might be able to get some rims from commercial garage, they would need to have the same offset, PCD for the studs and centre hole, failing that Linda at stateside would be a good bet.
No idea on the price £100 maybe?? As for location, mines in the bedroom slide locker, Shanes is in a carrier underneath. Scotjimland was talking about getting a carrier made up for his spare, so he could fit it underneath, I think he had a quote of over £200.
Suzy, I can ship you a wheel (minus tyre) but we are too late for this shipment. If you want me to get a price have a chat with me when we get back at the end of the month
RR John isn't a mile out on cost but they will vary depending on size and manufacturer.
