Ok rebuilding the front end on my 70 Coronet. I went to install the tie rod to the lower control arm. And the tie rod stud is spinning. It looks like the nut might be to the end of the threads without pulling the tie rod in. Because the hole for the cotter pin is higher then where the castle nut is now. Anyone had this issue. Am I suppose to use some sort of spacer on the tie rod? These were form a DR. Diff rebuild kit. The centerlink side had no issues. Thanks in advance.
