Unless you really need stock, many people move up to the early '70's C-body parts. They are a little more heavy duty, less expensive and bolt right up.

I went through some old info and I'm pretty sure that I ordered these from Rock Auto when I did my '68 Charger.

Tie Rod Outer (2) (74 New Yorker) moog ES352R $21.79
Tie Rod Inner (2) (74 New Yorker) moog ES355RL $21.79
Tie Rod Sleeves (2) (74 New Yorker) moog ES440S $16.53

I'm sure one of the smarter guys can jump in and confirm.
