There is an excellent tool for setting this up available from Jerry Bickel Race Cars. Again, however, it is for a four-link, not an IRS rear suspension. When I get home this evening, I'll post up more info and pics from the Bickel tool.
If it were a 4 link, the anti squat neutral line would pass through the rear tyre contact patch as the Diff wouldn't be constrained.

Since it is IRS the neutral line has to pass though the spindle and intersect the COG and Front spindle interaction.

As seen here:
