All half doors were lockless until around 1989 or 1990. I forget exactly when they started adding locks. I would prefer lockless myself because locks on half doors are stupid and pointless. Unfortunately though, parts are now unobtainable because you need parts for an only 3-4 year span vs all year of YJs or even TJs.
Door handles are the biggest offender because no one makes the lockless version and while I haven’t tried nor do I know anyone that has tried (due to rarity), I’m pretty sure you can’t just install the lock version onto a lockless half door.
