Just picked up my new (rebuilt) rack at auto zone. (Only took 2 tries to get one as labeled at 3.0 : 1 ratio - thanks for that heads up!!)

Removed the inner tie rod to add the extender only to discover a drastically different thread size than is on the extender.

Ever seen this? Wanted to check here before I take it back and try and explain why I want my money back after removing the clamps that hold the boots on.....
