I think you can fabricate a ball mount so you don't have to split your wishbones, but it may well need to be lowered which will hurt your caster...which can be solved by some careful cutting and welding on your wishbone arms...

Like every modification, it leads to another, and another, and another...

I'm not aware of any 'modern' transmission, manual or auto, that will not require crossmember surgery...
