That's an easy one from the Camoteksystems builds file. Yes they do look some what alike. Front left and right rear lowers same. Same going the other way, Front right and left rear lowers same. A way to tell is looking at the spring saddle. Springs to the front and spring to the rear.
No flipping / mixing or matching on the uppers all different, but easy to identify.
Then there's the A0 / 1 & A2 with different ball joint mounting holes 5/16 up, 3/8 dn or 3/8 up, 7/16 dn. Can have a smooth bushings or knurled bushings. And on the bottom different jacking holes and beefier ball joint mounting ???.

There they are. NO guessing now. These are AO junk. The top arms shown first and third are rears.
Front right note curves stamping with slight cut-out for spring of arm. Ball joint mount forward of center. Spring to the front
RIGHT REAR. Rears look more like mickey mouse ears where they mount to frame cups. Straighter balanced look. IMO
