While competing in a rally back in August the 1967 Sunny was pulling to the left under braking.  It got worse during the event but somehow we won anyway (very low key event so don't be too surprised).  We thought it was brakes but as soon as I started removing the front wheels I found the real cause.  The little tower on the left hand side that comes up from the front rails that the top suspension arm mounts on had broken off.  All that was holding it on was the bolt to the outer end of the cross-member.
 
So please check your cars, and has anyone else had similar happen?
