Looked for part number ALR6963 can’t seem to find it anywhere. Need a passengers side rear door lock/latch it seems there is a few different kinds out there after early one for 1994 4.0 located near Birmingham. Also is the lock simple to change or do I need a professional.

Early models use same latch from (a much cheaper) car. I forget which one - do a search on here. It is something you can DIY yourself but it’s not a ‘nice’ job.
