Check the thread direction on the two tie rods.
One needs to be left hand and one needs to be right hand.
I believe what you have will be the same "thread direction".
www.performanceonline.com sells a tie rod adapter that will connect the '82 outer to you old stuff,... but you have to use '67-'70 "outer" tie rods (as inners) with your '82 outer tie rods.
Your 82 outer should be 11/16" diameter and your '70 stuff will be 5/8".
Hope this helps.
