My 64 2 door sedan has been sitting in the garage for over 20 years until I recently decided to "just get it on the road". In the process of addressing all the potential safety issues after having sat that long, I was removing the idler arm for service (it was shot) when i noticed a crack in the frame on the passenger side just behind where the front subframe connects. You can see the mounting holes for the now removed idler arm to the right in the picture. Has anyone seen anything like this before? I'm not aware of any collisions in the past. I thought the car was in pretty good shape.
