Locking fuel cap help!

Hi - I picked up my 1985 defender 90 on Friday. She still has the original fuel filer cap which is a big black metal thing with a small hole in the middle and two metal lugs on the cap.

I tried to find a replacement locking filer cap as I sometimes have to leave the car in a public place overnight and dont want to have the diesel pinched but I cant work out which one I need from the various websites.

Has anyone purchased a locking fuel filler cap for a 1985 90 (used to be petrol)? Can you point me to the right webpage please?

Thanks, Rich

you cannot get a locking cap for early 90's, they changed around 86 to locking I think. Better off buying a new filler neck assembly with cap. they are narrower than the early ones so the locking caps dont fit.
