We have a Shelby in shop now with same pair of spindles that cob428 has and both cars are built same week. Cob428 did an older resto years ago and may have removed the double wire wrap (like I did on a car 20 years ago thinking it served no purpose until I started documenting the wire ID wrap on big suspension spindles). The car in shop now was partially restored back in the 80s and probly restorer removed the wire wraps also. So we now know we can document some c8oa spindles were machined for big suspension rotors.
