Ball joint replacement

Are those bushings needed for later models too? Mine is a 75 ! Iv already ordered my bushing I just got factory replacement bushing! If it's a huge deal i can order more.

Yup, the stock bushings were the same for all of them, and you can’t get much caster at all without the offset bushings. If you plan to run radial tires and have a decent alignment, the offset bushings are pretty important.
