I would also grind the caliper, I had to do the same years ago with pretty much the same wheel, I ground them down at Discount with their grinder, did not take much and 10 years latter I could not even tell where i ground them down.
if you grind the wheel, you have 40 some places that will now rust.
spacers, never ran them

If they are barely scraping I would grind the caliper as there is NORMALLY plenty of meat to them. That will be your quickest and easiest solution.
