Matt,
I don't know if this helps, but according to the 75 MPC, 6 cylinder Mustang and 6 cylinder Falcon power steering tie rods are the same. If Comet used Falcon suspension components, then yes. What you need to do is find a Comet forum and ask just to be sure.
C4DZ-3A130-C - RH outer
C4DZ-3A130-D - RH inner
C4DZ-3A131-C - LH inner
C4DZ-3A131-D - LH outer
The sleeve for Falcons, C3DZ-3310-A does not say I6 or V8, but it says 1/2-20 threads. It is different for Mustangs.
