if you get a different brand than the original , it may have a few more threads or a few less the collar may be a touch longer or shorter
I was replacing inner and outer and adjuster collar in the middle
this is what mine look like , going by threads wasn't going to work it was clear with 2 different brands of tie rods cause it was what napa had that they had different numbers of threads not a lot different but different and an adjuster different than original and some of them had already been replaced the only measurement that was going to work was
center to center of each that got me really close but even that wasn't perfect when on the alignment machine they were impressed how close I was.
I was also working from old parts that were being replaced for a reason
if you were having zero issues before replacing and you marked on the shaft and measured to center you could get very close to what you were at , but you don't know if that was exactly right , again you are replacing them for a reason.
if you want to do toe in as a home alinement you can lift spin and scribe the center of each tire then get very close measuring them front and back and adusting , you would need to look up the set toe-in/toe-out as they are typically not exactly zero but zero would be close
the catch you have to do it with the tires on the ground naturally so you need the slider plates or set the wheels on car dollies and roll back and forth to let them neutral pressure out
or if your line was permanent enough you could drive back and forth a ways then measure again front and back and adjust your steering wheel strait
to straiten your wheel make turn one side x turns then do the other side the same number in the opposite direction until the wheel is strait and you go strait and the toe is set
