Help! I need to identify my upper control arms please! 70 dart.

it used to be this was the one true way to tell, but now with the availability of SBP rotors for the 73~76 set up it can throw you for a loop. add into that the upper ball joint adapters and it could really go either way.

seeing the brakes and measuring the joint is the only way to 100% confirm these days.
SMALL BOLT PATTERN ROTORS, for the 73-76 A body cars?
6 cylinder Drum brake car?
Why in the world would you want anything like that?
I haven't heard of that at all, till you just brought it up.
Ok then, who has them, who do you get them from?
Not to go off track, from the original posters question(s).
