What is the difference between the 68-72 and 73-76 lower control arms. I can see where the sway bar tabs are located in different places, but the ball what else is different?
There is No difference in A body LCA's from 1962-76. They are all the same. It's where the sway bar mount tabs are welded onto the arm, if it's equipped with a sway bar. 65-72 tabs are welded onto the arm, low, near the ball joint hole. 73-76 cars have the tab welded on in the middle of the arm. There is NO difference in the ball joint stud hole diameter, in any of the years.

I'm almost sure the lower control arm are dfferent from 1973 to 1976 and the arlier ones, the hole for the lower ball joint stud is different. I found that out when swapping the front spindle and ball joints off of my 1971 Duster to the later 1973-76 spindle, upper and lower control arms and brakes I know many people think there the same but try fitting the 1973 and later ball joints, upper and lower, into the early arms You can ream the holes out to the larger size to make them work but they don't fit stock

That is not true. You are misinformed about that, for some reason or another. Ball joint stud hole diameters are all the same throughout all the years. Nothing at all changed in the LCA's.

, what is different is the knuckles on 73 up , they accept the larger B/E upper balljoint and the Upper control arm is different 73-76 A body .
That is if the car has disc brakes or 10" drums. There were a few cars built with 9" drums. Those still used the small upper ball joint.
I edited my post above because I neglected to include every possible brake option .

I doubt that. Try and find more than one A body UCA in any 73-up parts book.

This issue pops up often. I wonder how many naysayers have ever cared to look under a 73-76 A body. They are not the most desireable of the A body cars, so I doubt that many that doubt the existence of a post 73 9" drum brake has ever looked very close. Don't believe everything that you read in books. I have no financial interest in convincing anyone that they were built. I just know that in 18 years of junkyard doggin' I have seen several. I OWNED a 1976 Dart with so few options, you'd think that a person ordered it as a joke to see if Chrysler would build it. Slant six, 904, 9" drums at each corner, and an AM radio. I should have kept the fender tag because it was the simplest I'd ever seen. It's odd that so many agree that Chrysler built some wierd cars but will still insist that every A body after 1972 had front disc brakes. I've read that at some point in 1976, the feds required front discs on every vehicle. THAT I'd be willing to believe, since my '76 Dart had an October build date.
If you actually read what I said I made no mention of the 9" brakes. Nor did I insist on anything about disc brakes after 72. Your story of the 76 with "9" drums at all 4 corners" will not pass the sniff test. There were no 9" drums after 73. V8's after 73 were all disc brakes. By 1/1/1976 they were ALL large bolt pattern disc brake cars. Period.

I guess i will get involved in this depate one more time about 9 inch brakes on the 73-76 A body line of cars. For 35 years, i would have told you the same thing that no such cars ever existed. 73-76 A body's with 9 inch, small bolt pattern, brakes on them. Within the past few months, i have come across two 74 Plymouth Valiants that had 9 inch brakes on them. In all rights, they should have been 10 inchers, but these cars appeared never to have been wrenched on in their lives. So until you actually see one, two, or more of them in person, it convinced me that Mopar did lots of stuff that was supposed to never be.
