We are sorry you are having issues with your kit. We have sent you replacement ball studs for the various reasons you have described - you should have received them by now - actually, it might be while longer given how long Canadian mail took to get you your kit to begin with.
The best way to create clearance if you having issues is to tweak the fender lip downward at the area of interference. This will not harm your vehicle and will allow the ball stud to sit untouched in your vehicle.
Feel free to return the kit for a full refund if you are not able to get it installed to your satisfaction - we can't think of any other changes or mods for you to try to make it fit perfectly on your vehicle.
Thanks for posting your issues and for contacting us as well.
Thanks, Brian Redline Tuning
