Small ball joint vs big ball joint

[barracudakid]

I have a new pair of lower big ball joints 73 duster.
Will they work on a 69 barracuda SBP
Kelsey Hays disc brakes?

I may be incorrect but believe the bolt hole distance is different to the spindle.

Thanks

Can you make it work?

 

[Joey4speed]

Isn't the shaft of the big ball joint a larger OD?

Upper ball joints are large and small. Lower ball joints all have the same size stud. Their difference is in the bolt holes to the spindles.

 

[barracudakid]

That explains why lower arms are the same

 

[Jim Lusk]

No, they will NOT work.

No, they will NOT work.

What he said ^^^^^

ALL Lower control arms are the same thing from 1962-1976.
The only difference is if you have a sway bar, then tabs are welded on for 1965-72 sway bars, and then 1973-76 sway bars.
Ball joints bolt to the spindle, (knuckle) and the ball joint stud goes thru the lower control arm.
Spindles are different for 9 inch drum brakes, 10 inch drum brakes, 65-72 KH disc brakes, 73-76 drum brakes, 73-76 disc brakes.

Is it because of the distance between the mounting holes

Is it because of the distance between the mounting holes

Yes.
