Two wheel questions I've never seen

Actually, the centerbore was always wide enough, so I'm wondering if you're looking at the correct area where the machine work was done.

The material that was removed is not towards the "back" of the centerbore (nearer to the center of the vehicle), it was at the end of the centerbore near the centercap. I've modified the picture I uploaded to indicate where I had the material removed to allow for clearance of the allen head bolts. Once the wheel cleared those bolts, the rest was history.

I'm guessing I know where you're talking about -- though it did look like there was a 1/4 rim cut into the backside of the centerbore. (Which made me think WTF? LOL)

Can't see your new pic though...I'm guessing you used another name and deleted the old one -- because "LINK NOT FOUND".

I just replaced the first one with a modified one that had the same file name, and while it shows up if you click the link in my post, it doesn't if you click the link in your post that quoted mine. Seems like lost sock in the dryer stuff to me, but rather than figure it out, easier to just post the pic itself this time.

I'm guessing the machined section at the back of the wheel was for vehicle fitments that required a hub centric ring, but as tom4b mentioned, ours are lug centric.

Anyway, the material I had machined out now allows room around the outsides and the cap ends of the stock allen head bolts on our front hubs.
