you may need to wait for someone else to chime in but I believe 71 front end mustang stuff should fit comets and maverick front ends.
Most of the stuff should bolt in with the exception of the sway bar. The arms in the picture show a 4bolt ball joint but I don't know for certain if the arm is different otherwise. I know Mustang guys use Maverick spindles for disc brakes but maybe someone else knows for sure. I'm pretty sure the sway bar won't work though.
