the steering geometry is different from gen1 to gen2.. so its not practical or cheap to do ... taller balljoints installed with 67 spindles accomplish the same... (the spindleheight is measured from joint to joint, so taller spindle with stock joints, or stock spindle with tall joints are the same...)

you can for between 450 and 750 dollars rebuild your front end, and get an adjustable upper arm that will yield geometry thats equal to or better than the heidts spindle.... (and the heidts spindle plus 4 ball joints is much more expensive to)
