Fisher Fury Rear 4 link Adjustment

[Dyno Des]

Hi,
I am looking at setting up my Fisher Fury Rear Suspension for Drag Racing.
Whilst I have raced lots of cars for lots of years, I have never seen a 4 link set up where the top links face backwards.
In the past my cars have had fully adjustable asemetric 4 link or adjustable ladder bar rearends.

The Fury ( z ) box section 4 link has no adjustment at all. Has anyone any information on how to modify this type of rear end setup, and any advise on adjustment and settings for maximum traction.

I am running 22 x 10 x 13 Hoosier Hillclimb slicks,

thanks, Des
