Upper A-arm

[Larry's Shee]

Looked at son's Blaster other day, and front looks wacked. Seems that right spindle sits to straight up&down (no caster?). Had new arms on that side (crash damage, is big dent in frame) when purchased for $100 (lol). Is it possible P.O. put a left arm on it? In other words, are they close that it would be wacked but not redily noticeable?

i dont thin it matters which side a arms are used, as long as top goes up top and bottom goes down below. but the spindles are directional.
could be a bent frame causing the funny look.
