Re: Crack in the cross member

I'm not sure that the 76 Mustang II front end that I have out in the pile of stuff still has the struts on it so I'll doodle up a drawing that I hope explains it.

Ford used the struts on a number of cars in the 60's and 70's and they tend to work pretty well unless someone dinks with them and changes thier geomentry.

The concept here is that the spot where the bushing that holds the strut in the back should be perfectly centered on the line though the center of the bolt that the control arm pivots on.

The issue is that back in the 80's a lot of guys used to heat and bend the strut so it in their opinion better lined up with the frame. That changed the geometry but from what I have read in the past it put the control arm in a bind more than anything else and I don't know if it would cause stress on that area. That may have another cause.
