Most LT arms for a yfz are +2 and run 18.25 inch shocks. As the owner of a professional fab shop, dont try to make arms if you know nothing about engineering or geometry. Just because someone can weld doesnt mean they can make arms. If you are going to try to to this the arms MUST be in a jig of some sorts. Also there are many variables you have to take into consideration: spindle inclination, ball joint or heim joint spindle mounts, preset caster or adjustable caster via heims on top, gullwing or spud style lower shock mounts. If none of this makes sense then dont try making arms, you will only get yourself hurt.
