How can this swaybar work?

[Jeff]

There are tons of types of endlinks at both of those websites. This panhard bar dosn't see much movement outsde ot the up and down. Its sole purpose (or so it seems) is to keep the axel aligned as it moves up and down. Do you guys think I could get the "general purpose" steel ends for like $8.50 or should I go for the $26 each hardened? I don't want alum. and I don't think any of the exotic $60+ ones are called for either.
