Check out Crook brothers ( I know, it it sounds like a joke !) at
www.crookbrothers.co.uk They are specialists in MOD veh for over 40 years and can outfit a Rover any way you want it. Or pick up a copy of Land Rover Owner International and look in the ad pages. The last copy I had must have had 5 or 6 different MOD surplus dealers. Talk to them as they will be able to give you exact info and pricing on MOD Rovers in the UK
