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?
Quote: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 brakesQuote:

There is No difference in A body LCA's from 1962-76.
There is NO difference in the ball joint stud hole diameter, in any of the years.
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
Quote:After reading this I want to clarify that the cars I was swapping parts on where a 1971 Duster with stock disc brakes, I was swapping parts from a 1973 and 1974 Duster, one of the LCA was bad on the 1973 Duster so I took one off of a 1974 to finish the job. I don't know about the drum brake spindles, ball joints or LCA
Depends on the car that you are talking about.

, 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 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.

This topic still is a room divider. I've parted out several A bodies over the years and can only offer what I have seen.
Yes, there were SOME a body cars built after 1973 that had front drum brakes. SOME were 10" and used the large upper ball joint. ALL front drum brake A body cars used the small 5 on 4 bolt circle. The steering knuckle that the brakes attached to are different from the 9" to the 10" brakes. The '73-76 Disc knuckle is also different.
Over the years there has certainly been parts swapping done to these cars and I am sure that cars have been found to have "factory" parts switched to them that they never were available on that particular car. Case in point: I owned a well used up 1976 Dart Swinger that had a Slant Sick, 904 and 9" drum brakes on all 4 corners. I posted about this here and was told by many members that NO A body after 1973 came without disc brakes. THEN a few posts trickled in about...."Ahh, Maybe a few drum brake cars slipped by as Chrysler was using up their inventory....
I do not claim to be the GALEN on junkyard A bodies, I just recall what I have found. I've seen several 73-76 A body cars with front drum brakes. I will admit that many of the cars that I have seen MAY have had their original disc brakes pulled and someone MAY have swapped drums back on..... but how could that have happened so many times?

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.

I appreciate the discussion....i looked real hard on both lca from the two spreads of years. both lca ball joint holes look the same and when i tried fitting a 73-76 ball joint stud, the ball joint fit down inside the hole on both the 68-72 and 73-76. From the array of control arms i tried, some were more worn than others and sat somewhat deeper on the tapered shaft than the others. But that appeared to be a wear issue on the lca and not the balljoint stud. Like some others, i assumed that the lca ball joint studs were larger on the 73-76 A bodies and from what i see from the parts i have, that is not the case.
