Are there early and late style lower control arms? Or are all ball joint control arms the same?
Thanks

For a Super Beetle? Yes, halfway through 1973, VW redesigned the control arms so the ball joints press into the arms from below. Prior to that, the ball joints were attached to the bottom of the strut itself and passed through the control arm from above.
The early style control arms are forged. The later type are stamped and welded.

This is a standard not a super.
I bought a narrowed beam from a vendor on The Samba. It is a fabricated beam not a modified stock beam. He insists the lower control arm outer bearing diameter is the same on a ball joint beam as a link pin beam. He is incorrect. He said he has used the same beam on his own 66 beetle and his lower control arm bearing diamter is the same as a link pin. He told me I should use link pin bushings instead of ball joint bushins. Basically, what he is telling me isn't going to work. He also said I should have my lower control arms turned on a lathe by a machine shop to be able to use his beam.
Anyway, I am getting the feeling that he has never tried to use one of his fabricated ball joint beams. Admittedly, he said he mostly deals with link pin beams.

This person is a total idiot, I am not a machinist by trade, but I do have a small machine shop in my garage. There are many problems with trying to turn the arm down. First there is no way to grab it with the lathe chuck, it is the wrong shape. You would essentially have to build a turning fixture from about 1-1/2" solid round stock. Then use a mill to shape half the length into the shape of a leaf pack. After that slide it into the arm and use the grub screw to hold it into place. Now the fun part, in order to swing the arm, the lathe would have to be HUGE. The kind we see in black and white on PBS making bombers, and things like that.
To protect the rest of us, you really need to point out who the vendor is, he is worse then EMPI.

Ball joint uppers are the same inner and out and the lower inner is the same but the outer is definitely larger and the bushings will not interchange.
