TR3A front suspension question

["Paul Schneider" <schneidr@mc.net>]

I am re-doing the front suspension on my TR3A.  The cast lower left rear
a-arm was bent.  I bought a used replacement.  It was bent worse than the
one I took off.  The replacement for the replacement was the wrong part. The
replacement for the replacement for the replacement is the correct part, but
it is also bent slightly (down 3/32").

Are bent lower a-arms typical on TR3A's?

Opinions on how much this will affect the front suspension?

I debating to get a fourth replacement, or just go with what I have.
