Tie rod ends, what is the difference?

use the beefer ones as it makes a world of difference. numbers maybe different here from this article but you get the meaning here:

11/16" tie rod upgrade

The 11/16″ tie rod and sleeve set-up that works in virtually all muscle-era Mopars, A, B, and E-body, are just stock replacement 1974-’78 C-body parts. ‘74-’77 C-body Tie Rod ends bolt into place of the stockers, and are thicker/more rigid to resist torsion/bending while turning. You will have to use the C-body adjusters, but a cheap way to improve your handling. Tell the guy behind the counter that you have a 1975 Newport or some other landbarge.

74-77 C bodies used a beefy 11/16″ tie rod setup. These will bolt right up to your Challenger and give some added strength but look completely stock. These are also Moog numbers.
