Lower Ball Joint ?

[Nu2Mopar]

I am installing a disc brake set-up off of an F-body (spindles, rotors, calipers) onto my A-body 70 duster, I bought 73-76 (A-body) lower ball joints / steering arms and they are not threaded. Did I get the wrong ball joints or do I just need to use a nut and bolt to secure them to the spindle? If so, where can I get a short headed bolt so that I do not have bolt to rotor interference?

Thanks for any help or suggestions!

The ball joints are correct, they are nut/bolt setup, and yes the are low profile head type bolts.....now as to where to find them....

I just went to Ace Hardware and got some #8 bolts and nuts and it seem to be ok (no interference). I'll see once everything is bolted in and tight but it looks to be good so far!
