Hey champ...
I recently bought an F78 and have been looking into lifts also.
I found raised springs for $220 to lift the rear 40mm... fit some bigger tyres under and give some more clearance.
You'd also need shocks and Ranchos were about $250 a pair.
You can raise the front by winding up the torsion bars.. but new heavy duty ones will cost about $530...
That was through 4wd1.biz...
Ironman also do a lift package (DAI011bkg) which is raised coil springs, torsion bars and 4 shocks..
I'll let you know if I found out any more info mate.
P.S- Your bullbar looks sweet as... where did u pick it up from??
