is the taper on the tie rod ends of an early A (ES319) and the late A (ES401) the same? also....is the ball joint tapers the same? Just wondering because I'm getting ready to get ball joints, TREs and bushings for our project: 73 UCA/spindles mated to early A LCAs and centerlink. Which TRE should I use? either? so whats the difference between the two??????
