The spherical bearing is a Johnny Joint with the outside shell welded into the trailing arm. That sleeve has C clips that retain bearing cups on both sides. I don't think these Johnny Joints are available anymore.

I have similar looking offset trailing arms like BBShark and want to retrofit in the Johnny Joints like he did. Currie Enterprises is the manufacturer of these if I'm not mistaken and should be able to answer any detailed questions on their use. It's on my to-do list for next year.

Van Steel does, I basically want to make mine in the same fashion. Johnny Joints didn't exist yet, or at least I wasn't aware of them at the time I bought my trailing arms 20+ years ago. With the arc of travel the arms make, it makes more sense to have a spherical joint in that location. The original rubber bushings let you get by with it, urethane isn't as forgiving.

Van Steel makes an upper link kit. It used to be the Dragvette setup. The only issue I see with that is the axle is still a suspension link and your options for controlling camber are limited (without binding). To sort of fix this you could take the retainers off the side yokes and allow them to float in and out. The problem there is that the side yoke seals are lip seals and they are not made for reciprocating motion.

Karsten addressed that on his by having telescoping halfshafts built if I'm not mistaken. Modern cars get around that with CV joint style shafts that are able to move in and out of one of the drive cups. With U-Joints, the only way seems to be telescoping shafts. I agree that letting the side yokes slide in and out would only cause trouble in a hurry.

That's what I did:
