I don't participate much here so I apologize in advance if this has been covered before... I have a 74 Rx-4 - front rotors are hammered. Do any other rotors fit on the stock spindles or am I looking at a swap?

 

Best to upgrade to 81-85 front suspension and brakes. Its a direct swap. however, strut tube is shorter but it can be extended and the brake hard line end fitting need to changed to match the 81-85
