Outer Limits 4x4 Board

Hi ive just recently gone to replace my gq power steering box which is a big bolt power steer box. i went and bought a new power steer box from a wreckers and didnt realise that i bought a smaller gq power steer box. the new box fits in the car perfectly only problem is that when the steering arm comes up to the pivit arm of the box the steering arm hits the chassis before it can bolt in. Amy suggestions please????

Got a picture? I swapped the small steering box into mine before I sold it and it fitted fine.
