The Agency Power auto-to-manual line is the full thing (MC to SC). That's all you need. Look at the fittings:
$40

I plan on getting one, because I bent my hardline the wrong way and I can't use the clutch bracket with my SS clutch line...so mine just dangles.
EDIT: errrr...looks like Im wrong? That guy on the first page said he's using a clutch line + this long one.
