ball joint issues

Although I probably shouldn't admit it, in my younger days I launched my Barracuda on more than one occasion by travelling over a particular dip in the road. Just guessing, the car flew maybe 50 or 60 feet, maybe farther, & landed hard, with stock 9" brakes & new J.C. Whitney lower ball joints. I also had stiffer than stock shocks, heavy duty rear springs, & 340 torsion bars. I actually dented the oil pan one time. The ball joints never failed.
A friend of mine looked at the information page that came with the ball joints & said it looked exactly like a Moog info sheet without the Moog name on it. I should go back there someday & measure the distance. I know the city later reworked that dip in the road. There used to be a lot of gouges in the pavement on the far side of it where cars hit after the drivers were caught by surprise.
