After scratching my head regarding these tie rod ends not "looking right" and the boot being basically destroyed, I spoke with the guy I purchased the front disc assemblies from and found it was from a 73 Newport and NOT a 73 Satellite.
I was told the Satellite had the same tie rod ends as the Challenger which is what confused me- but there IS a difference when you compare the Challenger ends to that of the Newport.
I'm going to run down a set of these- as they need to be spot-on if the alignment guy is going to get this right.
