I have front disc brake issue, front spindle mounting bolt hitting sway bar mount on MBM disc brake kit? Need your help

NO idea what you are doing. NONE. So let's start with the basics

WHAT make model year car?

WHAT sway bar? and what year? And do / did your lower control arms have the tabs, or what

And WHAT is this brake kit? AKA is it a remake of the popular 73 and later factory style brakes, or something else, and if so, what exactly

I WILL tell you this. Many of us, who converted brakes, in my case 67 Dart + 73/ 74 factory Duster/ Demon brakes, I swapped the spindles and the calipers side for side, so the calipers are at the REAR of the spindles
