BIG problem here ... need help

Hi,

I was replacing the upper ball joint on my 72 Dart , on passanger side everything was ok got the ball joint tight to 125 lb-ft. But on the driver side, when I started to tight a little bite (not even close to 125lb-ft), the thread just stripped !!! :evil: :cry: :puker:
Now what can I do? :scratch:
Is there another solution then finding another control arm (cuz here they are pretty freakin rare...and we still have a couple of feet of snow everywhere :puker: :puker:)?

I hope you can help me with that, thanks.
