Guess I've struck gold on mine...

Today I was looking for the source of a (suspension) noise when turning to the right while slightly braking. Under the left front of the car a loud 'knack' can be heard everytime.
While removing the left front spindle from the lower balljoint, I remembered a topic here about A-body frame damage caused by metal fatigue.
I examined the frame rails on my car and yes, I found a serious crack running from the bottom of the rearleft K-member mount to the side and up to the bumpstop bracket. Haven't checked the pass.side yet.







I also think I found 'evidence' that the inner fender, and/or shock brace is are flexing enough so they contact each other sometimes.
I'm thinking of welding an angled bracket to both of them and make this area much more resistant to flex.
What dooes one think about all this?
