I love his other EBay listing for a LHD Defender and his main selling point over other RHD trucks is do you really want to drive on the wrong side of the road?
What an absolute moron.
I would say its a Warn 8274 winch.
I would also adjust the driver's side bib and apron so that the hood comes back into alignment. It may also be the hood hinges that need adjusting.
Looks like that winch was manufactured in 1981 and your truck is a 77, so unless that truck sat on the dealer's lot for 4 years, it probably wasn't a dealer installed option at time of purchase.
