Yes, #5 is the inside door handle. It's $13.35 on Merlin's parts site.
Merlin does have an ID here, but he told me he's never is on the forum.
He usually answers that number, but if not, just ask for him by name in the Parts Dept. I've found that number often goes to voice mail..which means they're busy...don't bother leaving a message, better to keep calling until you reach him live.
Also, he doesn't really like to use email...just call until you get him live.
Here's St. Charles online parts website...it shows you the same prices he gives us including the free shipping:
