just done this very job . on the ramp. what a pig of a job. most of the retaining clips will break, the route taken by the old steel pipes is difficult to get to , especially where they go between the body and chassis across the vehicle at the rear above the axle. the air tank will need removing to get to the pipe clips behind, not to mention the route to the brake booster/ master cylinder. took about 4 hours of faffing around :5bbanghead:
