I was looking at hotchksi tie rod sleeves and it says:

Machined wrench flats allow quick, easy adjustment. Fits 64-70 and 78-88 GM A and G body, 82-up camaro firebird.

So does this mean all steering parts (tie rod, sleeves, etc) are interchangelabe between those cars?

 

it means the threads opn the sleeve are the same and the length is the same, or close enough to work. very good chance a lot of other suspension and steering parts would interchange too
