Broken handle and broken locking mechanism

My door handle is broken and I bandaided it for a while but now the locking mechanism is broken and it won't latch . What do I need to order to replace the inner, outer handles, and locking mechanism that has the hook that latches the latch. It is keyed . I'm looking for the whole replacement . 82-086 matches my dimensions . What is the difference between 82-086 and 82-087? Does 82-086 come with the latching mechanism? I guess it's called mortise lock

Thanks for the reply and your expertise . That is the same measurements I got from the existing piece . I'm going to place my order . Thank you
