63-70 are one size, 71/72 are yet another size and 73-87 are yet another size. If yours are larger than your 70's then I would suspect you have a 73-87 spindle on there, just because 71/72 aren't prevalent and I would think you would know it. 73-87 tie rods have the largest threaded end.

Good luck!
