´70 Valiant / Upper ball joint

Hi Guys, have got a ´70 Valiant 4dr in the shop, needs some attention at the front suspension. It´s originally equipped with the KH disc brakes. I ordered Moog K704 ball joints for the UCA, now i´m not so sure if these are correct.....the ones that are installed do have a bigger wrench size than the new ones. The new ones do have from flat to flat around 1,75".....can´t even find a tool for these. Do i have the wrong ball joints for this application? I searched and ordered the part via Rockauto, don´t think they have a mistake in their catalogue....

If the BJ is correct then a hint regarding the right tool would be great!

thanks in advance!
