I have a 93 Z28 and I kinda ran off the the road into a ditch and the front right wheel is turned to the left compared to the left wheel. Me and my dad are thinking about just rebuilding the whole front end, as in new sway bar, tie rods etc. Would it be worth it to rebuild it all? If not, what could be wrong with it to cause the wheel to be turned like this.

 

U probably tweaked your alignment possibly bent the tie rod rebuilding the whole front suspension or at least the lower control arm bushings and new tie rods and sway bar bushings and end links is a smart choice just to make it feel tight upfront again being a 93
I'd thro in a rag joint eliminator kit as well if you have lots of side to side play in your steering wheel

 

Your A-frame, or whatever the piece is called that bolts to the wheel assembly and the cradle, may have slipped. I had this happen on my 96 and one of the wheels was cockeyed. There are three bolts that hold it. When you get a front end alignment, these are the bolts that are loosened and tightened to hold the adjustment in place. One or all of these might have slipped place, and you should be able to see it on the black paint where they were if they did slip. All the bolt heads face the ground so they're easy to see.
