How can I adjust wheelbase?

Thanks for the replies. The strut rods are the same length side to side, my kid did compare them when things were apart. I'll need to get the exact numbers side to side for the wheelbase / hub-to-hub measurement, but the right side is definitely a greater distance apart than the left. Maybe you are right and the K member is out of alignment? I did have it loose at one point to weld some cracking on the right side frame. It had busted out the captured nut at the rear K member mount on that side. I located it in the original position and welded it back in place, but I did have things kicked loose in the process. It sure didn't look like there was room for it to move much, but that makes sense to try moving the K member around a bit.

Again.....Is there any trick to pulling the strut rods without pulling the whole torsion bar and lower control arm loose again?

Thanks
