If using a 289 motor you probably don't need the higher capacity cooling fan. ERA provides a good sized radiator and the standard fan would probably work fine unless you have some really hot weather.

Twoshelbys brings up a good example about the roll bar. if my car is typical, it included the mounts for the driver side roll bar, although I ordered a street roadster without the rollbar. If you may want a passenger side bar then that needs to be fabricated in at their shop.
