Have you considered the wide axle hilux/4runner axle options.

Here is a link to what I was going to to my sporty with my old 4runner axles.http://www.4x4wire.com/forums/favlinker.php?Cat=0&Entry=24267&F_Board=UBB70&Thread=1029160&partnumber=&postmarker=

Gearing at 5.29 running 32's I worked out to be around the same as running 30's on the Sporties standard gearing. I kick myself now for selling the diffs when I bought the 80 series. I am now selling the 80 and keeping the Sporty.

Cheers, Chris
