I have an '04 NA GP, 267k miles.

I was going to change the subframe bushings today, but on the driver's side (rear bushing) it appears that the nut broke free. I think there is supposed to be some kinda tab that keeps the nut from spinning. Now the bolt (and nut) just spins.

There is a little square plastic access panel, but I couldn't seem to get a wrench in there.

Do I need to take the car to a body shop so they can cut & weld some sheetmetal there? Or is there another way to grab that nut so I can remove the bushing?

Thanks,
