You'll likely need two taps, (it is an oddball, it is a 'ford' thread) a left and a right hand so that you can take equal amounts off each side.
You can also get threaded bungs from SoCal and maybe speedway and weld them into a new piece of steel tube and screw new tyerod ends into it, again right and left hand.
High quality taps are available from McMaster-Carr, speedway seems to get a lot of stuff from china
