Upper control arm I.D. or I think I got took

Here are 3 sets of UCA's I just found out today while painting them that 2 pair of them are bigger than one.I bought the pair on the right at a swap meet in April, was told they were A-Body. Busted my but yesterday removing the bushings on them.
The Tubular ones, I bought from a member here about 3-4 yrs ago. Was told they were A-Body.
The small ones I bought on this site last year. I think (hope) they are A-Body. Was checking them over today, to dsee if I had all the bushings out, and thats when I noticed the difference in the two factory pairs.
Are the small ones for Abody,???. What are the other larger pair,???. they are all large ball joint.
