Going to do an SAS on my 87' IFS Pickup, and I was wondering what I need to do with the Steering Box. Can I leave the IFS one in and use it? Or do I need to swap in the steering box from the Solid Axle Truck Im getting the axles from? Thanks.

 

If you also include a high steer as part of the SAS then you can use the ISF box.
Good luck....and enjoy

 

Thanks.

 

Yea, my is also a 87 and I changed the frame from an 85, check my build thread

 

Youll want to use the IFS steering box.

Plating the frame where the box mounts is never a bad idea either.
