Crooked K-Member

Check it with a 4-wheel alignment rack or a thrust angle alignment. I'll bet the K is just where it belongs, and you're getting an optical cue that is messing with your brain,lol.
You can also put it on a frame deck and string it. The frame has reference holes and points just for that purpose.
I have the alignment machine here but have been trying to dial in the large issue before fine tuning. It is noticeable how much the left front tire sticks out compared to the right. I wanted to get the track in line with the rear before correcting the camber/caster in the front. The thrust is fine now as I replaced the warped rear leaf packs with new Hotchkis set and measured center to center on both sides.
