i bought them as 73-76 a body for my disc brake changeover on the 71 dart. got them sandblasted and painted and went to put them on and the lower bj holes are 1/2 a hole longer than the lower ball joints. i looked and see that the upper bj for a 71 monaco are the same as 73-76 a body but cannot locate lower bj other than rare parts. no listing at napa or rock auto. are these c body spindles? tia. rick w.
