Ross' '71 dart swinger

I HATE LEAKS!!!! The used 360 car pan I bought had it's drain plug over tightened at one point and striped when I tightened the drain plug. To get the car running and back to my house a universal rubber plug was installed and it leaked like a sieve, so today I picked up an M14 x 1.25 and a corresponding tap, I then drilled and taped the plug hole, now the plug is nice and snug and doesn't leak!!!! The best part is an M14 plug will take a 9/16 socket. (And it doesn't leak!!!!)
