i had that same problem on my cousin's 69 Camaro- when he had the tie rods that came with a cheap front end kit, they threaded in nice all the way. but when he upgraded to beefier Moog tie rods, they only go in about 3/4" or so which isn't enough to get the tires straight. lack of money forced him to quit working on it and the car is in storage, so we haven't figured out what to do about it. i told him to just get some stock replacement sleeves and sell the Hotchkis pieces, but he's dead set on using them because they look cool and he spent a lot for them 6 years ago.
one other thing- the factory powder coating or paint or whatever Hotchkis uses on them started to flake off when the car sat in an unheated shed for 3 years. the car never ran, and no tools were used to put the tie rods together so the finish was pristine when he put the car away. when he pulled it back out last spring to work on it, the links were rusting and he had them recoated with the control arms and subframe.
