Tubular Upper Control Arm Vendors

The heim joints on that setup may make noise over time. No bumpstop plate, no reinforcement at the ball joint and limited adjustability. Where's the upside again?

Yeah, dunno really. Maybe some adjustability to The camber? The steering arms are not correct either. I think some new ball joints and bushings with some chassis black will set me right. Do you recognize the brand of these puppies? Would help when I go to sell them.

Thanks for your time

The upside is the increased caster compared to stock. And, I don't see how there's "limited adjustability" either. The camber bolts would work just like they would with the stock UCA's and you already have more caster built in, so they're no less adjustable than the stock stuff. A shop that can set an alignment on a torsion bar car shouldn't have any more issues with those than the stockers. In fact, because you can screw the heims joints in or out a bit you would have more adjustability, the only issue with using the heims is you'd have to pull the UCA's out of the mounts to adjust them, that set up isn't adjustable while it's in place. And you wouldn't be likely to find a non-custom alignment shop that would be willing to do that, you'd have to adjust the heims yourself. And of course you would want to make sure you had enough threads engaged, there's some adjustability there but it's not unlimited. You would need to either move the bumpstop or switch to a rectangular one or something so that there's a downstop on the suspension to keep the UCA's from hitting the frame. And I'm not a big fan of heims at the UCA for a street car, they wear out faster ( at least in my experience).

As far as the brand goes, based on the design and lack of markings I would be inclined to say they're from Magnumforce. Mopar A Body Adjustable Tubular Upper Control Arms There's a chance they could be the older design of the RMS arms, but they had RMS stickers on them. Based on the welds they aren't the old CAP arms. Most of the rest of the tubular UCA's have a gusset plate at the ball joint with that design, but I could be missing something.

Hate to bug you at all now, but where would a guy source quality upper n loer ball joints and bushings for a 67 barracuda? With K/H setup of it matters...

Again, thanks for your time.

It looks to me like both your UCA's and your lower ball joints are for a 73+ style spindle. Do you have spindles on the car now with the KH set up? The KH set up will not work with the later spindles, you'd need KH disk spindles and they use a small upper ball joint.
