Wow Thank you Mechanic Mark! 11/16"-18 thread is not common but apparently used by fords also. I got mine from Speedway Ford- $10. I had previously called Applied Industrial who I thought knew everything about tie rod ends- they could not find...
This is an old thread but, to clarify I bet the above poster got the wrong part as Jacobsen uses the even more uncommon 5/8 x 18 thread on the 628 tie rods and not the 11/16 ".
