Does anyone know the size/thread of the HP (the big ones) lines for the power steering rack. Will a push in plug work, or will there be enough pressure in the rack to push them out.

I would like to remove the HP lines and plug the rack not cut and crush them.

Thanks!

Edit This if for a 92 if it matters.

I also don't want to pay the $50 for the Miata roadster kit.
