Excellent, thanks for this.
I know there is a DIY replacement that involves using a generic actuator but if I can replace the genuine part with OEM I would rather do that, and if a Z one will fit the GT then that is easily sorted
Now to find a door lock and I will be even happier
Nick, I forgot about the aftermarket door actuator for the G35 and the kits are cheap as chips from USA @ about $10
There are plenty videos for this on youtube and looks very straight forward and only requires the door card removed and a few extra holes drilled and a couple of wires snipped, extended and re-routed.
However you will still require the lock and barrel in your instance.
