Brake rotors for 1972 3.0Si (euro)

[Brewster Pettus]

The rotors on my 1972 3.0Si are warped and need to be replaced. They are all vented with the fronts approximately 254x21mm and the rears 254x19mm. I seem to have trouble finding replacement rotors for the fronts. I can find front rotors for the 3.0CS but no measurements are provided. Does anyone know if they are interchangeable? If they aren't, does anyone have any suggested solutions?

Thanks in advance.

Same part numbers front and rear in the Orange books for e9 and euro Si. In the US the e3 never had vented rotors.

Thanks, Chris. Is that a euro version the e9? I was under the impression that the e9 had drums in the rear.

I think that's only for the 2800's. The 3.0's all got rear disk

Correct, and all vented.

Look on Ebay.de. I found mine at Ireland Engineering but that was 3 years ago.
