Overall Assessment

Customers affirm that our product exhibits great utility and quality, fitting perfectly once the sleeve is removed. They value its versatility, as it successfully adapts to various models like '35 Chevy with mustang 2 15' wheels, and a '46 Chev Truck. Though longer studs and installing new races for bearings required additional effort, it still performs well, upgrading 9in brakes to 11in. The product offers significant improvements over rival offerings, thus most customers willing to recommend it.

Studs had to be replaced with longer ones and then had to take the rotors to a machine shop to remove the GM bearing races to install the Ford bearing races!

Good so far!
