Do disk brakes of a 1973 vw bus fit on 1969 beetle?

The disk brakes of a 1973 VW bus will not fit on a 1969 Beetle without modifications. The 1973 bus uses a different spindle and caliper mounting system than the 1969 Beetle, so the brakes would need to be adapted to fit. Additionally, the 1973 bus uses a larger brake master cylinder than the 1969 Beetle, so the master cylinder would also need to be changed or modified to work with the disk brakes.
