Yup a three jaw to pull, and you can buy a long piece of threaded rod that threads all the way into the crank and a nut to install, or a guy on eBay sells them.
Also make sure you have the correct oil pump/pick up tube o-ring and install it carefully. Can't always go off what color came out of it if it had been worked on previously.
The timing cover/seal needs to be centered around the crank when installed also
