addco 751 sway bar for 1963 Dart

I know this is old post but anyone have a measurement from center of eyelet to center of eyelet on the sway bar. I have a helwig bar part 55914. I’m installing on my 64 cuda and seems to be too wide. My measurement is 44”. Nothing like the pic in their directions. Pic has the endlinks vertical, mine follow the angle of the shocks. TIA.
