just needing a little help with a brake conversion. I have a '69 1602 with a 320i motor, I also have the rotors from the same car. Im not sure of the year of the donor car, but I believe it is late '70's. I have been told that the disc can go straight on, but i think that the hub size is different. What is the story? can I use a different hub that will fit my original struts?? Any help is apreciated!! thanks!
