Holtz Racing tie rods for 1K question

I have bought a set of the Holtz HD tie rods for my Xp1K and have not put them on since my OEM ones are still fine but the more I look at the Holtz ones the end that goes into the steering rack looks identitcal to OEM and I was wondering if anyone knew that to be true or have tried to just attach the Holtz tie rod and wheel end to the OEM end coming out of steering rack?
