Steering stops

Can someone tell me how the range of steering full left to full right is adjusted? Normally there would be steering stops but I don't seem to see any??

EDIT: Okay I see what I think are the stops but nowhere to adjust??? My thinking is to weld a 3/8" or 5/16" nut onto the lower A arm position and then have the bolt go out to the spindle stop with a double nut for locking??
Thoughts, concerns?

That’s often what you see.
Manual say anything?
A little change changes the turning circle noticeably.

Tires rubbing?

Funny thing with my 13" wheels and tires on it was a problem but now with the 15" wheels all good!!!! The only thing I can figure is it must have been the rim hit the upper control arm, 15" seems to clear all that. Not going to question a problem that fixes itself...LOL

Backspacing?

Yeah that could be it as the rims are wider so that may also be true, never checked.
