What is the difference between a pre-1975 and 1975 Opel hub? Here is a picture of my current hub/rotor. I'm wondering if this is the stock setup for a 1972 GT or possibly it has already been upgraded to the 1975 Manta hub and bigger brakes.

Thanks,
Bob

Thanks, I just checked and they're 61.5mm pads riding on 48mm pistons. So, I guess I still have the pre-1975 hubs.
