Your wrong, my dart had the LBP conversion done but the guy front mounted them in the front and they interfered with the sway bar. I rebuilt the front end,swapped sides on the spindles and calipers no problem.
No, I'm not wrong. There are calipers that are designed for rear hung applications and they are different than the front hung calipers. Just because you didn't use them on your car doesn't mean they don't exist.
