Super II pickups can be either F spaced or Gibson (standard) spaced. Note that F spacing only applies to the spacing of the pole pieces -- the physical size of the bobbins is the same for both F spaced and standard spaced Dimarzio humbuckers. The SDS is longer overall and is only available in F spacing.

On my guitar, mounting the SDS parallel to the humbuckers made it stick out too far on either side of my E strings, so angled it forward 19 degrees:
However, most folks don't do that, and Garcia didn't do that on his guitars, so I guess you have to decide for yourself how you want to handle it.
