Go to McGard.com and put in your information. After that, it depends on whether the nuts need to be acorn shaped on the ends to just sit up against the wheel or whether they need to go through the wheel. Ask about it when you go to buy the wheels. When you know which style and number you need, you can check to see if there are any on Ebay.
Ok, I found out the wheel stud size- 12x1.5mm. But how do I know what type of nuts to get - I am getting these wheels used and am having a hard time getting specs on them. What do you mean by sitting up against the wheel or going thru, and is there an easy way to visually make that determination? Thanks
