    Slotted 80-81 GS rotors on a 78 GS1000

    Can anyone tell me if there is a problem fitting the slotted rotors from the 80-81 GS1000 using the existing calipers (round pucks)?
    I have installed the newer rotors on my 78 GS1000E with the bolt holes lining up perfectly but I now can't get the old calipers to fit onto them. Also, the distance between the rotors and forks seem to be different per side too (I believe I assembled the axle and all the spacers correctly).
    I also have a newer set of calipers (square pucks) that look like Suzukis to use but I'm not sure. The bolt holes to the legs seem to be slightly off if they are.
    Help!
