Noticed just now that the left A-Arm on my car met a curb hard at some point.

Come on, Mark ... that'll buff out

'Early' or 'late' control arm?

I have either late or early. let me know.

What’s the difference between early and late

There is no difference between early and late.

The only difference is sway bar tab or not.

I have a set with tabs and a set without if you need.

Have a set as well.

Only difference on A arms is with or without sway bar tabs. They are not early and late.

That was easy.. Thanks everyone!

Didn’t some have a little tab to hold the ball joint from turning and some didn’t?

Functionally no difference, but early arms had the locating tab welded on, late arms had the tab punched & bent from the arm.

I prefer the bent tab, it doesn't break off like the tack welded one does if the ball joint spins while removing it.

Thank you.
