Are '73-'76 drum brake upper control arms large ball joints? Thanks
NO, they are not. The 73-76 drum brake cars were small bolt pattern which had the small ball joint control arm. They used the small bolt pattern all the way to 1976 in the A bodies and with that, retained the small ball joints which used the small hole upper control arm.

You are correct about certain things, and you are wrong about others.
The 1973 to 1976 A body cars were all big ball joint, wether it had drum brakes or disc brakes. It made no difference what so ever.
You are right in the statement that drum brake cars, were the small 4 inch bolt pattern in 73 to 76.

Then what makes the 73 - 76 disc and drum a arms different
Ok.....well let me say this then. My 73 scamp musta had the drum brakes swapped out on the front for more drum brakes. It had small bolt pattern suspension with small ball joint upper control arms. Disc brakes were not on the build sheet or fender tag, so somebody swapped drum for drum. How stupid does that sound to you? If I am wrong, I stand corrected. It won't be the last time.

It is possible that a very early build 73, during the first week or two, of production, could have squeaked by, with the small ball joint UCA and small hole spindle.
But everything else was a large ball joint upper A arm.
So '73-'75 ('76 cars had disks standard) with 9" drums had small ball joint upper control arms
how do i identify whether i have a large or small upper ball joint?
are the 10 inch drum spindles the same for discs???
