Steering Tie Rod Inner Miata 1990-97

New inner tie rod for 1990-97 Mazda Miata.  Fits right or left side inner.  Mazda used two different styles of threads on the inner side of the inner tie rod.  One thread is about 17mm with 1.00mm thread pitch.  The other is about 17.5mm with 1.50mm thread pitch.  See picture for details.  OEM=Genuine Mazda.

Not 100% confirmed, but it appears that Coarse thread (1.50mm) is for a manual rack. Fine thread (1.00mm) is for a power rack.

The best thing to do is measure your old ones and purchase that size.
