These 8 lug spacers come in various thicknesses, try tire shops or even on line. You can't go to thick with the spacer, limited by stud length. Also I used some peal and stick rubber weatherstrip on inside edge of cap to give a bit more space.
This was on my flatbed so have no fender to worry about.
Good luck
