Trailing Arm Crack

["Richard Seaton" <RSH17@msn.com>]

  I have a crack in the rear trailing arm.  What I am wondering is if it can
be welded up. The reason for my doubts on welding, is it is cast aluminum. If
it has many impurities it won't take the weld.  Has anyone out there had luck
with this?

Thanks in advance.

Getting ready to start on the body, floors, rockers, etc.
