Transmission Cooler Line

[cgster]

How far does your transmission line screw into your radiator on the bottom line? Mine keeps leaking where the line screws intp the radiator. New engine and radiator (old transmission lines) so I hope I haven't striped out any threads trying to get it to go in. Really hate to have to replace the steel lines right now until I get it a little further in the restoration process, I need to move it around my garage and yard so I need to be able to crank and move it but would rather not till this line is fixed.
