Possible to upgrade 65 911 brakes to vented rotor setup?
 

I have a 65 911 with solid front and rear rotors, with the stock M-type front calipers. Has anyone done, or heard of a way to get vented rotors and larger calipers onto the front and rear suspensions, like the 67S and later (69- on) 911's?
It's not a direct swap, is it? If so, from which models will the calipers and rotors fit? I am under the impression that I have to replace the entire front suspension to get vented rotors. Is this the case? Any help would be greatly appreciated!
