i have a 2.0 dohc sierra at the minute and noticed it has no rear anti-rollbar and cosworths do , i done a bit of research on here am i right in saying an escort cosworth rear arb is a straight fit into the back of a sapphire all i will need to do is get 22mm arb bushes and drop links and weld some brackets onto my swing arms to attach the roll bar drop links to ? thanks
