Joe, do you not have a GT6 with IRS?  Or are you asking specifically about Todd's sliding-axle arrangement?

On the production GT6 Mk2 the upper control arm was the spring itself.  The axle's bearing was fixed firmly to the upright rather than allowed to pivot on a longitudinal axis with a trunnion as with a swing-axle.  See part #17 in the left-hand drawing at:

IIRC, Jaguar have used an arrangement in which a fixed-length axle with u-joint or CV joint acted as one of the control arms.  And Lotus has used the Chapman strut, similar to a McPherson strut but with the control arm replaced by a fixed-length axle and a toe-in control link.  But the GT6 never did, of course, and never needed a fixed-length axle.

Or maybe I'm missing the point of your question.
