TBH i think trimming the crossmember and reboxing it looks like it will get you where you need to be. If you have to clearance the stock tunnel a little with a minisledge i would have no problem with that. Easier to do than welding in a tunnel kit. Its a shame the car tool crossmember kit doesnt come with a template to cut the crossmember and a premade strap to box it back in.
