Are The '73-'76 Upper Control Arms The Same For Disk And Drums

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.
