´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!

It’s originally equipped with kelsEy Hayes, is that what is on the car now? What bolt pattern do you have?
