Hey, I got a 1992 reg cab 4x4 4cyl. It currently has (the way I just bought it) 32x11.50-15s on it. The tires look awesome on it, looks like there may be a slight torsion bar crank on it, but I cannot tell for sure as im not sure what is stock. What do the control arms look like in stock configuration? Perfectly horizontal?

 

Mine are almost or close to it, I'm one inch away from the bump stop, when I first got mine the torsion bars were cranked and I felt every bump in the rode lol

 

no they should not be perfectly horizontal, but close to it maybe 10* or so at factory height.
what's the measurement between the center of your front axle to the bottom of the fender lip?
I think at factory height, this measurement is somewhere close to 21" (or like 13.5-14" top of wheel to bottom of fender, less accurate measurement)
