Help identifying ball joint

[LightningMike]

My car had some aftermarket suspension parts installed before I bought it. I need to replace my upper ball joints, but I have no idea what brand the A-arms or Ball joints are. I'm hoping someone else has the same brand and recognizes these. The ball joints are screw in, which I've never encountered before.

arms that look like that with screw in versions are usually a circle track based part.look into Howe ball joints.i'd start over on speedwaymotors.com

Those look like chrysler type ball joints to me.

Those A-arms look like the ones that Robert Adams used to sell back in the day. I don't think he sells the kit anymore since all the links I've found are dead. Just to add to the confusion or to prevent you from falling to some gotchas...chances are with those A-arms, you have A/B-body spindles or possibly F-body spindles which means the rotor diameter could be 12" or 11" depending on which spindle you have. The Chrysler screw in ball joint does have a different taper to them so the GM spindle is reamed to accept so if someone decided to change out those UB machine arms to say GW or Hotchkis that upper balljoint taper would need to be addressed. Calipers, brake pads, bearings...all the replacement wear parts would be specific to the A/B/F-body vehicle and not the G-body. Ahhh that’s not entirely true 12” third gen f-body 1LE rotor for the 4 3/4” bolt circle…

Yeah, those look like an exact match to my A-arms. Thank you so much for all that information.
