Those fuel pumps for the Rocco, yes there's two, are not cheap. That deal would be worth it for the springs and header depending on what brands they are. Probably couldn't go wrong for all the parts for $500 though.

Another note about the Rocco, '84 is split year/mixed up year for them. '84 is when they switch to the large rear spoiler, space-saver spare, bigger fuel tank.
