Dude, you aren't really giving any information here. If you would tell us from the get go what you have done & what not, we wouldn't be taking stabs in the dark on this. By measuring a track bar, that doesn't do much. Those things should be the same length from rig to rig, as long as they are 78-79 with a solid axle 44. The other thing, some of those bushings for the back of the radius arm have caster built into them. If you have them installed wrong, that is going to shove things around too. Also the c-bushings have to be installed correctly too, there is an upper & lower side on each bushing.
