Canon should be able to sell it to you. Here is a link to a Parts List for the Mk I version: 1.4x Mk I parts list
(MOD NOTE: Link removed per Forum Guidelines) is an independant company that sells camera parts, but they don't have anyting listed for an EF 1.4x III

In that case I would send it to Canon Service. "Dropped" and lenses are not a good combo. Your converter may need to be checked out further.
