Can any one tell me if the spline number on ef fairmont axles with abs have the same number for the ef xr6 lsd diff, as ive fitted lsd xr6 diff but they dont have the abs component on them any help would be greatly appreciated

axle splines are 28 spline, and are all the same from,gli,futura,fairmont and xr6..
except not all have abs..

Yes they will work just fine. (don't forget the LHS and RHS are different lengths)
