Front suspension - uh oh!

["Chris King" <cbking@alum.rpi.edu>]

So I'm potting the rebuilt and repaired fron suspension back together
today. As I raise up the a-arm, compressing the spring, I fint that
there's about a 1/2 inch gap between the trunnion bushing and the shock
arm. So something's still twisted. It could be the a-arm, but it seemed
to measure out ok. It could be the frame, in which case I'm screwed.
 
Now, is there any way I could check the frame arms short of a body shop?
 
Anybody got a good A-arm to spare?
 
TIA
