Slightly used 10mm Ichiba wheel spacers-$49 Shipped

Those boys were in there like swimwear. I tightened them with an open ended lug nut. Like you said, the studs were too long. Do you know for which vehicle your new studs were made for?

Also, I have the same spacers and found that Ichiba ships with extended studs that are way too long. This makes it extremely difficult to get the studs into the mounting plate. The studs only need to be 10mm longer than OEM, and the ones they ship are more like ~20mm longer. I had to get more appropriate length studs from Napa.
