Hi can anyone help me. I have a 1978 delta 88 diesel. Does anyone know the rotor size for the front? Thanks in advance.

 

Diesel cars SHOULD have the HD brakes, which means the 12" rotors and 11" x 2" rear drums. Deltas without HD brakes came with the 10.75" rotors and 9.5" x 2" rear drums. Why don't you just use a ruler and eliminate any question about rotor size?

 

Thank you.
this is my first classic car. And I just want to be real-time careful about putting the right parts on. I will measure and go from there thanks joe!
