Now I might be wrong here but bear with me.
I am rebuilding the doors on my Vitesse 6 in preparation for fitting them to the body.
I had a look at the outside door handles and as we know the right one has a key lock and the left one just a button press, on lhd cars it will be the other way round.
A minutes staring and I came up with the idea of taking a barrel out of a spare rh door handle and swapping out the press button on the lh one. It all went surprisingly easy and looks like it will work once I get the locks keyed alike.
But will it work and is this all that is needed to convert both doors to key locks?
