Gives me some confidence because yours were worse than mine are. did you have clearance issues removing the lower fitting? i was worried about breaking the radiator or screwing up the female threads when removing the fitting. i know the upper line is high pressure and the lower line is return (lp) so the lower is much less likely to leak anyway.
