Hey Guys, Check out

I just bought mustang rotors for 124 shipped.
I also have previously bought the 4" bolt pattern rotors for $69 a pair shipped to my door. I have had good luck dealing with them so far & couldn't beat the prices anywhere else.
Thanks for the reference to this site John, can't wait to get the manifolds from you & try out the rotor swap on my 69 383 car.
