Getting delivery in a week or 2 just got email with vin. With the spacers any concern of not enough thread for the wheels?finally found the company that did mine. Was one of the one's I posted above.

search through their site to see if you can still custom order them online. Otherwise, give them a call.
I believe the Niche wheels have a bore size of 74.1mm, but every wheel is different. So just be sure you have the exact bore size for your wheel before ordering. Best of luck.
Thanks
