The only one left that I need to get is a non chafing manacle, but the guide doesnt have that listed to tell me what creature to kill to get that. What monster drops this?

After completing the Wishlist following the Rag and Bone Man quest, the list will have "Non-chafing Manacles" written on it. After completing the Wishlist following the Fur 'n' Seek quest, you may speak to the Odd Old Man to get an explanation about this

 

Taken from RuneWiki's page on the odd old man.

non chafing manacle means you have completed the list...

I speak to the old man and she just says that he has all the bones and that the museum appreciates it and tells me that he needs other odds and ends and to read the list, and the list says non-chafing manacles only....

Non-chaffing manacles is what the RAG AND BONE MAN list says when completed.

There is a separate list to click on for the FUR N SEEK bones on the other side of the door way.

 

See 2 separate lists.

Non-chaffing manacles do not exist.

thanks, I didnt realize there were two lists. Another related question, it says I need 3 tail bones, how do I know which dragons I have yet to give it?

I faced the same problem as you and I found the answer on RSOF. All you need to do is to click your quest tab and select the quest 'Fur N Seek'. Scroll down the quest guide to see what items have or have not been crossed out.
