Help! I need to identify my upper control arms please! 70 dart.

Both, and the whole shape of the arm is different. The big arm is beef when you look at it next to the small arm.

If the ball joints you installed fit reasonably snug even though the threads were stripped, I'd just tack weld them in another spot or two and call it good. That fix is fairly common on ball joints that were pressed out by folks who didn't know that they threaded in.

Yea, honestly, thats what I am gonna do. Replacement arms, aren't exactly easy or inexpensive. I can run in a new ball joint , tack it and hit it with some black spray paint and it will undoubtedly last the remainder of my years. This car will probably see no more than about 500 miles a year and not a chance of a single drop of water. I really appreciate originality, but I think I am gonna wave the white flag on this one. Thanks Mark.
