I bough these brake rotors as part of a front end replacement kit. So far I have only used them to mock up the front end but am impressed with the look and fit of them. They appear to be a good quality part and should look nice when finished.
Pros:
  • Nice Fit
  • Look Great
Yes, I recommend this product.

7/16"-20 -- It's listed as part of the details on the right side of the page.

This rotor has 7/16" studs and require lug nuts with 7/16"-20 thread. Acorn lug nuts such as 91041178 are fairly popular but the exact style of lug nut required will be determined by the wheel that you use.

These rotors are original for the 1973-77 GM midsize vehicles and are adapted to the early 37-48 Ford spindles with appropriate bearings and seals. If you currently have a Ford bolt pattern on your hot rod and desire a Chevy bolt pattern this would be the choice of readily available rotors, bearings, and seals. For part numbers for the bearings and seals feel free to call and visit with a tech.
