If you can't get the tierod to start threading you will need to tap or chase the threads out then. Good luck on finding one. Or try using a pick to remove the metal shavings off the threads the old inner tierod left behind. Just enough to get the tierod started in the rack.
Since this car has 110k miles on it you should replace the rear brake shoes once you got this done.
My friend bought his 2004 aveo with 120k miles and the 3rd day of owning it the driver rear brake shoe friction material came unglued from the metal support and locked up the wheel. I found this is very common with the stock brakes that came with the car. It required 1 whole day to use a slide hammer and axle puller to get it off if that happens. Even though the shoes looked good you can peel off most of the friction material with your fingers or a small flathead screw driver.
I recommend getting autozone's $50 brake drum with new bearing that is sealed for life with it since his came with serviceable ones. You will need a axle nut socket to remove the nut.
