Key locks

The factory arrangement ...

... and fitted

The after-market kit (parts for two locks in each kit)

As originally fitted to the V8 the driver lock stiffened up quite a bit with the grub-screws fully tightened and I had to slacken them a bit. Thinking that the kit distorts the lock very slightly and some necessary clearance was very small on that particular lock, I eventually got round to removing it and fitting it to my test panel to work out what needed relieving. I was surprised to find it wasn't stiff at all, nor when fitted back to the door. A mystery.
