I'm telling you, the Civic manual rack is junk. You'll regret swapping it in. Too many turns lock to lock, it will be like driving a school bus.

The rear subframe is different in a car with a stock PS rack and one without. The passanger side mounting surface is curved to leave room for the larger PS rack but the manual rack's surface is flat since the rack tube is so much thinner. I've been told you can wrap the stock manual racks bushing in the PS's bushing and crank the bracket over it and it will hold. Seems ghetto to me but it should work. I seriously suggest you keep your PS rack with the end's capped off or get an Integra rack and cap those lines and use it.
