Power Booster: 82-92FRemanufacturered GM original booster. .. no exchange needed.. fit it.. forget it.. These are not worth risking system failure on and pretty equal cost wise with getting an old one rebuild if viable "Depending on the type of RHD conversion, you might need to lengthen the pushrod between the booster and brake pedal. This can be done by any machine shop by cutting the pushrod and heat shrinking on a sleeve".
