is that a 2 gen or a 3 gen? I had an 84 that ran into a simular problem. Ended up being the frame cracked behind the steering gear box. common problem with this gen the front end was poorly designed. I had it sent to a local shop and they welded the crack and put in braces to help support the front. If this is not your problem you should be able to pick up the brackets at a local junk yard or through the aftermarket. I think year one sells the brackets you need.
