Just do a search for 'cam bearing driver' and you'll find options.
Be aware you're treading into territory a lot of folks avoid. It's not an easy process, even w/ the engine out of the car and the reciprocating assembly removed. And a mangled cam bearing will kill your oil pressure in a hurry.
The cam gear would have had to cross all but the last cam bearing, are you inspecting & replacing all of them or just the front one?
