Nope... sadly you gotta replace the whole end.
I wouldn't mark and measure them, aligning an XJ is fairly easy. There are two things you can adjust - toe in and wheel centering (drag link length.)
From what it looks like in that picture you will be replacing the TREs on the tie rod (one left hand, one right hand), the drag link itself (can't replace the end on this... sorry) and the TRE at the pitman arm (forget if this is left or right.)
Turn the wheel till you're driving in a straight line, park it. Measure the distance between two points on the fronts of the tires (mark the points.) Measure on the back too. Write the numbers down. Replace all the stuff, use stainless steel cotter pins if you don't like rust. Adjust the new tie rod ends till the measurements are the same. Adjust the adjuster between the pitman arm TRE and the drag link till the steering wheel is centered. Tighten all adjuster clamps, take it for a test drive, if it handles well, double check your measurements and call it a day, if it doesn't, either readjust or pay ~70 bucks for a professional alignment.
