yes - the stop stud is normal threaded into a hole - just loosen the lock nut and turn it out a bit - go in stages to see what works without restricting the turn radius more than necessary - seeing the wear mark on the tire, you musta polished that drag link cap pretty good

the tire can take it, the drag link can't - and drive it to check it - put some chalk on the knuckle or tire and make a couple hard turns, especially bumpy ones, the tires will pull further than they're turned when moving
the bungee on the brake line is understandable, they're hard to get set right to avoid rubbing - a slight twist when you tighten them on will usually do it, instead of making a nice smooth loop like that - what's more worrisome is that bolted on, welded up shock mount

hopefully those are grade 8 bolts, and the shocks are the correct length
