Jake, it's these ones you want.

They will outlast the other types. I take them off and roll moly-grease round the ball whenever I'm in that area doing anything, at least once a year.
I use stainless half nuts on them, but any M8x1.25 nut will do.
McGill's also list rubber boots for the rod ends, but I've never succeeded in fitting them satisfactorily. The Chrome-moly ones seem to resist the grit and grime anyway.
