Perfect!
I had the voltage regulator fail on my Z06, outputting up to 16.5 volts. This GM replacement is half what the dealer is charging and working great so far!!

Worked great for my C7 Corvette
OEM product worked great to replace my overcharging alternator. Re-used existing bolts and it looked exactly the same.
