PItman shaft seal installation advice

I have broken at least two harbor freight pitman arm pullers. It all depends on how tight yours is. Sometimes they can be a nightmare to get off. Getting the pitman off is the hard part, the rest is a 5 minute job.

I was going to buy this one from autozone since it's only $2 more than harbor freight. Would this be the correct size opening for our cars?
