I have a 67 mustang coupe with a 302, it’s got a cam and Intake and a Holley carb, the transmission has been rebuilt it’s a 3 speed automatic, my rear end is stock it has 2.79 rear gears. Every time I punch the throttle from a stop it makes a clattering noise coming from the rear, but it only does it when I’m at a stop and then goose it. It drives perfectly fine after I let off the gas and stops making the noise. I have no clue what is making the noise all I know is that it’s definitely coming from the rear of the car. Someone plz help me try to fix this issue.
