Replacement door locks

I bought a set of four with two keys for my 90 from a reputable seller on fleabay (shhh - it was! lol) a month or so ago, only to find when trying to fit them yesterday that the barrels are slightly too big in diameter for the sleeve they should slip into.

Are there different diameters for different years? Mine's a C-Reg '85

Help? Ta

No sure what door locks you have but the one's for yours are quite easy to change just a case of taking the small screw out the back of the barrel, put in the key, turn it and put out the lock. sounds as if you have been given the wrong ones

I agree, the original ones were very easy to get to and remove - I was just a tad annoyed I'd been sent the wrong ones to fit...Hm.
