I have been in the motor engineering business for 35 years and done land rovers for 14 years, You'll probably find that these bits are Britpart who supply most of the the OEM stuff, you can always ask before buying or get direct from Britpart at these prices. OEM only means who gives the dealer the best price, Land Rover don't make anything now, emperors clothes and all that and certainly the private garages will go for the cheaper NON Britpart bits that the motor factors often get, at least if you do it yourself you know what you have fitted, of course dependent on an individuals ability. Still, water under the bridge now.
