LOL! No worries, I wouldn't have known except that in getting these wheels custom machined and ready and looking for sizes to fit them that would look good and fit on my truck I've been over this like 1000+ times in the past 2 months!
They're wheels off a titan I had to have them machined then I painted them with automotive myself then had to make my own custom centers due to the center bore being drilled all the way through and out the front the oem centers no longer worked!
