15 or 16's all around

Is there any tire clearance issues after the Granada swap with the upper ball joint with 16 inch rims\tires? I remember a post a while back of someone wishing they would have gone 15's or 17's because the tire was so close to the upper ball joint. I absolutely don't want to go 17's.
 
I think it all depends on the UCA you have. Global west sales and recommends 16’s so that leads me to believe 16’s will work with their UCA. I have also seen where people have modified their UCA so they would fit. And of course the width and back spacing of the wheels will affect this as well. But we all know we wont the widest tires on our cars.
